RAWGraphs
Unusual chart types from a CSV, no spreadsheet wizardry needed.
RAWGraphs turns a pasted CSV into visualizations that spreadsheets do not offer, like alluvial diagrams, streamgraphs and circle packing. It is open source, free, and processes your data in the browser.
Best for: Use this when a bar chart will not cut it and you need a more expressive visualization.
Pros
- Chart types you will not find in Excel
- Data is processed client-side in the browser
- Exports clean SVG for further design work
Cons
- Not a dashboard or live-data tool
- No data cleaning, your CSV must arrive tidy
