StoryChart
Accessible data storytelling tool for educators and journalists who need to turn raw numbers into a chart with a narrative — generates the chart, the alt text, and a plain-language summary in one workflow.
Teachers, trainers, and independent journalists who need to publish data-driven stories
- Auto-generated alt text and audio description for every chart produced
- Side-by-side narrative generator that writes a plain-language explanation alongside the visual
- Embed-friendly output that renders properly in LMS platforms, Substack, and school newsletters
- Colorblind-safe palettes and high-contrast defaults that meet WCAG AA without manual tuning
TanStack Charts markets accessibility as a default; the obvious gap is a tool for non-developer storytellers who cannot configure that themselves
Accessibility pain is well-documented (Harvard, Accessibly.com, SWD) and tools like Datawrapper serve 'millions of readers' from newsrooms, but the specific 'chart+alt-text+plain-language summary' workflow is a feature-level need, not a stand-alone search category users google for.Data Visualizations, Charts, and Graphs | Digital Accessibility Services ↗15 Best Data Storytelling Tools — Juice Analytics ↗
Market is crowded with funded incumbents targeting the same users: Datawrapper (free + $599/mo Pro, newsroom default), Flourish (Canva-owned, $69/mo), Tableau Story Points, ArcGIS StoryMaps, Juicebox ($45/mo), RAWGraphs, Datastory.tech — most have some accessibility features but none bundle auto plain-language summary + alt text + chart as a single non-dev workflow.Datawrapper vs Flourish: Pricing, Features and Reviews ↗15 Best Data Storytelling Tools — Juice Analytics ↗
Target users are notoriously price-sensitive: independent journalists and K-12 educators rely on Datawrapper's generous free tier and Flourish's free plan; Tableau at $70/editor/mo is already considered high. Willingness to pay for another tool is constrained unless institutional/procurement sales carry it.Datawrapper vs Flourish: Pricing, Features and Reviews ↗Tableau Public ↗
Accessibility compliance (WCAG 2.2, ADA Title II, Section 508 for schools) is strengthening yearly; data journalism is institutional; AI-generated alt text and summaries are an expanding, durable capability rather than a fad.How to Create Accessible Infographics And Data Visualizations ↗
Build is largely composition: TanStack Charts (or D3/VisX) for the chart, an LLM API for the summary + alt text, a simple CSV paste UI, and standard web deploy — no novel primitives required.Developing Accessible Web Applications with TanStack React Charts Library ↗
