Richard Brath
TL;DR
The study examines the under-explored impact of LLMs on designing specialized text-focused visualizations. Through a longitudinal review of 55 visualizations and design reflections, it finds that LLMs facilitate design exploration and enable new design classes while requiring designers to remain actively involved.
Problem

Method
The study reflects on a timeline of 55 novel text-centric visualizations and their design artifacts to examine changes in the author’s design process.
Results
LLMs facilitate design exploration and enable new classes of designs.
Takeaways & Limitations
LLM collaboration supports design ideation and trades slow, precise coding for faster iterative exploration.
Takeaways & Limitations
LLM-aided design can skip data, hallucinate, lack graphical precision, and produce bland results without specific designer direction.
Abstract
from arXiv · showhide
This study examines data visualization design evolution over 12.5 years, reflecting on the impact of Large Language Models over the last 3.75 years. Using a longitudinal corpus of 55 visualizations from a single-subject design record, the study identifies how LLMs have aided design-space exploration: reducing coding effort, enabling new design opportunities, shock, excitement, accomplishments, and shifts to the design process.
INTRODUCTION
The study addresses the under-explored impact of LLMs on designing specialized analytical tools, focusing on text-focused data visualizations.
- LLMs’ impact on the design process for specialized analytical tools, particularly text-focused visualizations, remains under-explored.
METHOD
The study retrospectively assembles a spatial review of the author’s design record to examine evolving text-visualization design spaces. The corpus spans 55 visualizations and reflects 35 years of design and data-visualization practice.
- The author spatially arranges prior design artifacts to facilitate recall and reduce working-memory load during reflection.The review includes physical manipulation of printed artifacts, including folding and sticky notes.
- Text-focused visualization involves an evolving representation space and the encoding of potentially non-numeric data.
OBSERVATIONS
The observations contrast the uncertainty of hand-drawn visualization sketches with the lower technical burden and faster exploration enabled by LLM-assisted coding.
- The observations focus on how the design process changes before and after LLM adoption.
- Hand-drawn sketches left implementability, data-driven appearance, and expected patterns unresolved until proof-of-concept implementation.
- LLMs reduce the technical burden of learning libraries and writing code, enabling faster exploration from concept ideation through validation.Before LLMs, novel visualization concepts typically required lightweight JavaScript+D3.js or Python implementations.
TIMELINE OF NOVEL TEXT VISUALIZATIONS BY AUTHOR
The timeline records a progression of novel text-centric visualizations that expand encodings, text scope, interaction, and narrative forms. Across the record, designs range from exploratory typographic experiments to large-scale, interactive, and contextual visualizations.
- The timeline begins with novel encodings such as equal-area cartograms, positional text encoding, skim formatting, and quantitative underlines.These experiments test geographic visibility, text length, inverse word frequency, typographic formats, and perception.
- Later designs broaden the design space from typographic attributes to text scope, including letters, words, lines, and larger textual structures.
- Several experiments produced strong excitement, visceral reactions, satisfaction, or a sense of accomplishment, while others were frustrating, non-intuitive, or uncertain.
- The record includes increasingly complex combinations of textual visualization, such as data comics, sparkwords, letter-level bars, and dictionary-like treemaps.The treemap summarizes more than 2800 coroner reports while supporting filtering, search, and links to original documents.
- The timeline shows designs extending beyond conventional text visualization toward lyric analysis, narrative panels, and literal text treated as a data type.
23. Word sequences as a railway
These visualizations explore textual structure through sequence, size, color, and content, revealing both expressive possibilities and substantial implementation effort.
- 23. Word sequences as a railway: Repeated dialogue phrases can be represented through expanding text cells and hue-coded speakers.Examples include recurring phrases associated with Alice, the Duchess, and the Cheshire Cat.
- 23. Word sequences as a railway: Text size can encode quotation frequency to create visual landmarks of memorable passages in a full literary work.The approach was satisfying despite difficult data, unlike technically effortful neighboring designs.
- 23. Word sequences as a railway: Phoneme visualizations encode vowels by color and final consonants by texture to support lyric-structure and rhyme analysis.The design is described as highly satisfying and extending visualization beyond ordinary text.
- 23. Word sequences as a railway: Treemap cells can combine magnitude, quantity, grouping, and textual content, supporting a satisfying mixture of quantitative and qualitative information.Content inside large boxes provides an alternative to purely abstract metrics.
29. Multilevel graph🡢🡢
The later design record shows LLMs becoming collaborators, generators, interpreters, and coding partners that broaden exploration while retaining technical and epistemic risks.
- 29. Multilevel graph🡢🡢: Repeatable prompt recipes organized data description, visual mapping, layout, and interaction to generate varied interactive text visualizations.Examples included text scatterplots, beeswarm plots, distributions, and tables.
- 29. Multilevel graph🡢🡢: The author’s LLM roles expanded from text processing and collaboration to data generation, insight extraction, diagram generation, code generation, and annotation.The listed roles span October 2022 through May 2026 and include interpreting hand-drawn sketches.
- 29. Multilevel graph🡢🡢: LLM collaboration supported spontaneous ideation by making low-risk, low-cost experiments more feasible than before.Features explored included bendy tables, force diagrams, animation, condensed text, and rings of text.
- 29. Multilevel graph🡢🡢: The reflection identifies possible generative homogenization and emphasizes that designers must direct LLMs specifically because models often produce conventional results.The author characterizes the designer as remaining in the loop rather than beside it.
- 29. Multilevel graph🡢🡢: LLMs enabled new visualization opportunities including strategy diagrams, mindmaps, force diagrams, close reading, and text-rich tables.These projects extend computational visualization into diagrams, qualitative analysis, and previously difficult table designs.
- 29. Multilevel graph🡢🡢: LLM-aided exploration reduced design effort from days to hours, despite hallucinations, imprecision, and other tool-related issues.The shift concerns coding and prompting across design exploration, not only final implementation.
CONCLUSIONS
The conclusions present LLMs as accelerators of visualization exploration and ideation, while stressing delegation boundaries, persistent model weaknesses, and continued designer control.
- CONCLUSIONS: LLM-aided design remains constrained by skipped data, hallucinations, graphical imprecision, and tendencies toward bland or conventional outputs.The designer must remain in the loop and direct the model with specificity.
- CONCLUSIONS: Fast iterative LLM-in-the-loop work can trade off against slow precise coding when code is needed to validate and adapt ideas using real data.The conclusion frames this as a process trade-off rather than eliminating coding altogether.
- CONCLUSIONS: LLMs can take on subtasks such as finding data, scraping, processing, and applying visual transformations.Delegation is presented as one component of LLM-assisted visualization work.
- CONCLUSIONS: LLMs support design ideation by enabling iterative exploration and generating suggestions that can help overcome writers-block-like creative impasses.The stated benefit ranges from loose formulations to broad suggestion generation.
- CONCLUSIONS: Whim and serendipity matter because rapid LLM exploration can keep ideas from being skipped or dismissed prematurely.The conclusion connects lower exploration cost with preserving otherwise overlooked design possibilities.
- CONCLUSIONS: LLMs can facilitate design exploration and enable new classes of designs, potentially supporting new uses, applications, and software categories.This is the paper’s broad concluding claim about the implications of LLM-aided visualization design.
