Create charts including pie, bar, line, area, scatter, bubble, and radar charts.

Send "type": "chart".

Create charts including pie, bar, line, area, scatter, bubble, and radar charts. Only for plotting VALUES: a "chart" that plots nothing and instead shows how people or parts relate (org chart, reporting structure, hierarchy tree) is a diagram — use render_flowchart.

Also available as the MCP tool render_chart. The same payload works through either surface.
