Turn CSV into clean Tufte-style ASCII charts with a Mermaid-style `chart` code block. Plain-text bar, line, sparkline & scatter that work in READMEs, terminals & LLMs.
Generate ASCII graphs ▁▂▃▅▇▅▃▂ in Markdown and for plaintext use. CDN and Node packages make it easy to setup and use. Includes an Obsidian Plugin.
Use the block syntax:
```chart
sparkline "System Metrics — 24h"
CPU, 12 25 38 55 72 88 72 55 38 25
Mem, 30 32 40 55 65 72 78 85 80 70
Net, 5 8 15 8 72 88 18 5 8 32
```
To generate multiple graph types: sparkline, bar charts, line graphs, progress, histogram and more. All in plaintext.

One thing that stands out
the site is live, there's a playground, and assets are being served through a CDN, but I couldn't find a Privacy Policy or Terms of Service.
That's probably not a problem for hobbyists trying it out. It is a problem for anyone evaluating it for company use. The moment a tool touches an internal docs workflow, legal and compliance start asking questions, and "we'll add that later" usually ends the conversation.
I'd treat that as infrastructure rather than paperwork. A lot of teams won't even get to the product evaluation stage without it.
@felix_tongs really appreciate that. Great call—I'll add a PoC and ToS. In the meantime—using either the CDN or Node package provides you the full package, so there's no data ever sent outside your own app. On tufte.ai, there's no database, no cookie tracking, no event tracking—hence no cookies banner. Nothing is stored on my end, even with the playground is entirely front-end.
