Replaces four scattered dispatch locations (schema_validator, dataset_validator, chart_utils, runtime validator) with a central ChartTypePlugin registry. Each of the 7 supported chart types (xy, table, pie, pivot_table, mixed_timeseries, handlebars, big_number) now owns its pre-validation, column extraction, form_data mapping, post-map validation, column normalization, and runtime warnings in a single plugin class. Key changes: - Add ChartTypePlugin protocol and BaseChartPlugin base class (plugin.py) - Add ChartTypeRegistry with register/get/all_types helpers (registry.py) - Add 7 chart type plugins under chart/plugins/ with full coverage - Fix 5-type column validation gap: pie, pivot_table, mixed_timeseries, handlebars, and big_number now participate in dataset column validation (previously silently skipped) - Move BigNumber trendline temporal check to BigNumberChartPlugin.post_map_validate() - Add get_runtime_warnings() to plugin protocol; XYChartPlugin implements format/cardinality checks, removing isinstance(config, XYChartConfig) from RuntimeValidator - Fix stale generate_chart.py docstring listing only 'xy' and 'table' chart types - Add missing pie, pivot_table, mixed_timeseries handlers to _enhance_validation_error; refactor into a data-driven lookup table to stay within complexity limits - Fix empty details fallback in Pydantic error handler

Chart type plugins package.
|
|
|
|
Importing this module registers all built-in chart type plugins in the global
|
|
registry. This module is imported by app.py at startup.
|
|
|
|
To add a new chart type:
|
|
1. Create ``superset/mcp_service/chart/plugins/{chart_type}.py``
|
|
2. Implement a class extending ``BaseChartPlugin``
|
|
3. Import and register it here
