A new way to make graphs more accessible to blind and low-vision readers Designed to help blind and low-vision readers understand graphics, the “Tactile Vega-Lite” system from MIT CSAIL converts data into a standard visual graph and a tactile chart. Accessibility standards...

Tactile charts are an important tool for conveying data to blind and low vision people via embossed paper. However, tactile charts require high levels of time and expertise to design.

Introducing Tactile Vega-Lite, new work at #CHI2025 led by MIT SM student Katie Chen

Kicking off my first #30DayChartChallenge with something special: learning Shiny for #Python and leveling up my #vega altair skills to build interactive visualizations. My first chart has an interactive legend and zoom! Link to Shinylive app and code below 👇

Do you want to animate a @vega-vis.bsky.social vega-lite or @observablehq.com Plot chart? Here is a quick experiment that might help you that animates between two SVGs.
Let me know what you think! #dataviz.

For Severance (and custom visualization 📊 fans): @giammaria.bsky.social re-created part of the macrodata refinement (severance.wiki/macrodata_re...) UI in Vega. An impressive demonstration of what you can do in Vega.

Try it in the editor at vega.github.io/editor/#/gis...

Single-sided violin plot with strip plot below and a simplified box plot between the two.

I like single-sided violin plots. It's nice to use a tool that can actually make them. #Vega
