Description

Implement Plotly-based chart creation tools for data visualization.

Acceptance Criteria

Create mcp_server/chart_tools.py
Implement chart_create tool:
- Input: chart_type: string, data: object, options?: object
- Supported types: line, bar, scatter, pie, heatmap, histogram
- Data can be inline JSON or reference from data-platform
- Output: Plotly figure JSON
Implement chart_configure_interaction tool:
- Input: figure_ref: string, interactions: object
- Add hover templates, click callbacks config, selection behavior
- Output: Updated figure JSON
Both tools registered in server.py
Theme tokens automatically applied to charts (if theme loaded)

Technical Notes

# Example chart_create input
{
  "chart_type": "bar",
  "data": {
    "x": ["A", "B", "C"],
    "y": [10, 20, 15]
  },
  "options": {
    "title": "Sales by Region",
    "color": "primary"  # Uses theme token
  }
}

Dependencies

Depends on #170 (MCP server foundation)

Completed: Chart tools implemented.

Tools Added:

chart_create - Create Plotly charts (line, bar, scatter, pie, heatmap, histogram, area)
chart_configure_interaction - Configure hover, click data, selection, zoom

Features:

Theme color integration when theme is active
Default Mantine-based color palette
Donut chart support via donut: true option
Horizontal bar charts via horizontal: true
Axis labels and titles

Test Results:

Bar, line, pie charts created correctly
Invalid chart type returns helpful error
Interactions: click_data, selection:box, zoom:disabled configured
