ApexCharts

ApexCharts gives your assistant the official knowledge of seven JavaScript visualization libraries: ApexCharts, ApexGrid, ApexGantt, ApexTree, ApexSankey, ApexStock and ApexMaps.

Ask for a chart, data grid, Gantt chart, org chart, Sankey diagram, stock chart or map, and the assistant can generate a valid starting config, check a config against each library's documented rules (wrong series shapes, invalid options, missing required fields), and read the matching reference docs on demand. Every tool is read-only and works from bundled documentation, so there is no account to create and nothing to install.
