Trial Graphics: Types, Costs, and How to Brief Them

A personal-injury verdict is decided by twelve people who have never read an operative report, seen an MRI, or heard the word "radiculopathy" before voir dire. Every fact in the case reaches them through testimony they will forget by deliberation — unless something visual holds it in place. That is the entire job of trial graphics.

This guide is for attorneys and litigation support staff who need to decide what to build, what it should cost, and how to brief it. It covers the six categories of trial graphic, where each earns its cost, what makes an exhibit survive an objection, and the mechanics of briefing an illustrator or producing one yourself. If you specifically need anatomical exhibits, the companion guide to medical legal illustration goes deeper on that category.

What Counts as a Trial Graphic

Trial graphics — also called litigation graphics, courtroom graphics, or demonstratives — are any visual prepared to help a fact-finder understand evidence. The term covers a wide range: a one-slide timeline, a colorized MRI, a labeled anatomical illustration, a scene diagram, a damages chart, a thirty-second animation of a collision.

Legally, most of them are illustrative aids under Federal Rule of Evidence 107, which took effect in December 2024 and codified what courts had long permitted: a visual that helps the jury follow testimony, is not itself evidence, and does not go to the jury room unless the court allows it. Some graphics — an accurate scale diagram of an intersection, a chart summarizing voluminous records under Rule 1006 — can be admitted as substantive evidence. The distinction matters for what you can do with the exhibit, not for whether you should make it.

The category is older than the software. Attorneys used chalkboards, enlarged photographs, and hand-drawn anatomy on foam board for most of the twentieth century; the first computer-generated reconstruction to run at a major federal trial was the Delta Flight 191 animation in the late 1980s (see forensic animation). Digital presentation arrived in the 2000s, and by the 2010s jurors — who now expect information to come with visuals — treat a party that presents without them as less prepared. The graphics themselves have not changed in kind since the foam-board era: a timeline is a timeline. What has changed is the cost of producing them and the expectation that they will be there.

They are used at every stage, not just trial. A demand package with a clear injury illustration settles faster and higher. Mediators respond to exhibits because they show the defense what a jury will see. Expert depositions go better when the expert is walking through a diagram they helped build rather than describing anatomy from memory.

The Six Types of Trial Graphic

1. Timelines

The most-used and cheapest graphic in civil litigation. A treatment timeline shows the sequence of injury, diagnosis, procedures, and recovery; a liability timeline shows what the defendant knew and when. Timelines are where jurors first understand the shape of a case. In a malpractice matter, the gap between an abnormal lab value and the response to it is the case — and it is invisible in a 400-page record until someone puts it on a line.

Build timelines from the medical chronology, cite each entry to a record page, and keep one idea per timeline. A liability timeline and a damages timeline are two exhibits, not one.

2. Medical and anatomical illustrations

Custom drawings of the injury, the surgery, or the anatomy at issue, derived from the plaintiff's own imaging and operative reports. These are the highest-leverage exhibit in injury litigation because they make the harm concrete: not "a disc herniation" but this disc, at this level, compressing this nerve root. Before-and-after comparisons and surgical step sequences are the two formats that move damages numbers most.

The medical legal illustration guide covers the subtypes, and the trial illustration guide covers how to choose and label them.

3. Colorized and annotated imaging

The plaintiff's actual MRI, CT, or X-ray with the pathology highlighted in color and labeled. A radiologist reads grayscale imaging fluently; a juror sees fog. Colorization shows where the fracture line runs, where the herniation presses, where the hardware sits. Because it is the real image with overlay, colorized imaging is often the least-contested exhibit in the case — the defense expert is looking at the same film.

4. Scene, mechanism, and biomechanical diagrams

How the event happened and how force traveled through the body. Intersection diagrams for vehicle cases, fall-path diagrams for premises cases, mechanism-of-injury diagrams that connect a rear-end impact to a cervical flexion-extension injury. These bridge liability and damages; they are the exhibit that answers "how does a fender-bender cause a two-level fusion?"

5. Damages and data charts

Medical-bill summaries, lost-earnings projections, life-care-plan costs, and pain-and-suffering timelines. These are Rule 1006 summaries when built from voluminous records, and they are the graphics the jury takes into the number. Keep them plain: one chart, one conclusion, source cited.

6. Animation

Moving reconstructions of an event or procedure — a collision sequence, a surgical error, the mechanism of a spinal cord injury. Animation is the most expensive and most objected-to category. It earns its cost when timing or motion is the disputed fact and a static image cannot carry it. Our guide to animations and illustrations for trial covers when animation helps and when it invites a foundational challenge, and forensic and legal animation covers the production side.

What Trial Graphics Cost

Exhibit type	Typical cost	Turnaround
Timeline	$300–$1,500	2–5 days
Colorized imaging	$400–$1,200 per study	3–7 days
Custom medical illustration (CMI)	$500–$2,500 each	2–6 weeks
Scene / mechanism diagram	$800–$3,000	1–3 weeks
Damages chart	$200–$800	1–3 days
Animation	$5,000–$25,000+	4–8 weeks
Full exhibit package, complex case	$15,000–$50,000	6–10 weeks

Two things have changed the economics.

Budget for presentation as well as production. Firms that use graphics heavily at trial typically retain a trial technician — sometimes called a hot-seat operator — to run the exhibits in the courtroom, so counsel is never fumbling with a laptop in front of the jury. Rates run roughly $1,500–$3,000 per trial day. For a two-exhibit case it is unnecessary; for a case built on a forty-exhibit sequence it is the difference between a presentation and a demonstration of how not to give one.

On production: First, trial presentation software (TrialPad, TrialDirector) made it cheap to show exhibits, so the cost is now almost entirely in producing them. Second, AI-assisted illustration has collapsed the cost of the static anatomical exhibit. A tool like Natomy produces a labeled anatomical illustration from an operative photo or imaging study in under a minute, which puts illustrated exhibits within reach of demand packages and mediation on moderate-value cases — matters where a $2,000 illustration never made economic sense.

What has not changed: any illustration used at deposition or trial still needs a qualified expert to review it and testify that it is a fair and accurate representation. The savings are in production, not in foundation.

Admissibility: What Makes an Exhibit Survive

The objections you will face are predictable, which means they are preventable.

Foundation. A witness with knowledge — usually the treating physician or retained expert — must testify that the graphic fairly and accurately represents what they are describing. Build the exhibit with that witness, not for them. An expert who first sees the illustration the morning of their deposition will hedge, and hedging is what the defense wants on the record.

Accuracy to the record. Every material element should trace to a document: the level of the herniation to the MRI report, the hardware to the operative note, the timeline entry to a dated record. An exhibit that shows more than the record supports gets excluded or, worse, admitted and then dismantled on cross.

Rule 403. Even an accurate exhibit can be excluded if its probative value is substantially outweighed by unfair prejudice. Graphic surgical detail, dramatic color, and emotional framing are where exhibits get cut. Restraint is a legal strategy, not just a design preference.

Disclosure. Most scheduling orders and local rules require demonstratives to be exchanged before trial. Missing the deadline is the easiest way to lose an exhibit you paid for.

AI-generated content. Courts are paying attention. The Judicial Conference's Advisory Committee on Evidence Rules published proposed Rule 707 for comment in 2025, addressing machine-generated evidence offered without a human expert. Illustrative aids sponsored by a testifying expert sit outside that rule's target, but disclose the production method if asked, and make sure the expert — not the software — is the one vouching for accuracy.

How to Brief a Trial Graphic

Most bad exhibits come from bad briefs. Whether you are commissioning a certified medical illustrator or producing an illustration yourself, the brief should answer six questions.

1. What is the one thing the viewer must understand? Write it as a sentence. "The L4-L5 herniation is left paracentral and contacts the descending L5 root." If the exhibit needs two sentences, it is two exhibits.
2. Who will sponsor it? Name the witness. Their opinions define what the exhibit can show.
3. What records does it come from? Attach the operative note, the imaging report, the relevant deposition pages. The illustrator should never have to infer anatomy.
4. Where will it be used? A demand-package image can be detailed. A trial board needs to read from twenty feet. A slide needs to read on a courtroom monitor at 1080p.
5. What must it not show? Anything the expert has not opined on. Anything the record does not support. Anything that reads as advocacy rather than explanation.
6. When do you need the first draft? Build in a review round with the expert before the deposition or exchange deadline.

Send the brief with source records, expect a draft, review it with the expert, and iterate once. Exhibits that go through three or more revision rounds usually had an unclear brief, not a bad illustrator.

Building Illustrated Exhibits Yourself

For the anatomical illustration category, it is now realistic for a firm to produce a first-draft exhibit in-house and send it to the expert for review, rather than waiting weeks for a studio.

The workflow: pull the relevant operative photograph or imaging study from the record, generate the illustration in a clinical style, label the structures that matter to the opinion, and run it past the expert with the source record side by side. Natomy's accuracy checker flags anatomical inconsistencies before the expert sees the draft, and the guide to generating medical illustrations walks through style choices. Keep every exhibit editable until the expert signs off — a labeled layer is far cheaper to change than a flattened image.

For timelines, damages charts, and colorized imaging, the tooling is ordinary: presentation software for timelines and charts, and the imaging viewer's annotation tools or a radiologist for colorization. The tools attorneys use to interpret medical evidence covers the chronology and imaging side of that stack.

A Short Checklist

Before an exhibit goes to opposing counsel:

• One conclusion per exhibit, stated in the caption.
• Every material element traceable to a record page.
• Reviewed and approved by the sponsoring witness, with the review documented.
• Readable at the size and distance it will actually be shown.
• No color, motion, or detail that adds emotion without adding information.
• Production method known and disclosable.
• Exchanged by the deadline in the scheduling order.

Trial graphics do not win cases on their own. They make the case you already have legible to the people who decide it — and in injury litigation, legibility is most of the fight.
