Functions exposed to the LLM to take actions

Name	Description
create_chartA	Describe a chart semantically (bar, line, area, pie, doughnut, radar, scatter, qr, graph, gauge, …) and get back a permanent, hosted Image-Charts image URL that renders server-side and embeds anywhere. No client-side chart library required.
image_charts_urlA	Escape hatch for full control: pass raw Image-Charts parameters (cht, chd, chs, chco, chxt, chxl, chm, …) and get the hosted image URL. Signs the URL automatically when icac is provided and IMAGE_CHARTS_SECRET is set.
list_chart_typesA	Discovery: returns every semantic type accepted by create_chart, the Image-Charts `cht` it maps to, a description, and which inputs it reads — plus the concepts Image-Charts cannot render.
