Charts / Sankey

Sankey

Rendered by viz_render in OODS Foundry 0.10.1, in each theme, from sample data this site supplies.

Generated from @oods/foundry 0.10.1

No named pattern draws this type, so this site supplies the data: Visits to paid accounts in a month (made up).

Each chart is drawn live in your browser from the spec viz_render returned with it, so you can point at its marks. The SVG viz_render returned is the record: its hash is under each chart, and it shows where a live drawing would differ from it.
