<!-- Answer --> The correct `viz_type` for a bar chart in Superset 5.0 is `echarts_timeseries_bar` (not `bar`). The legacy `bar` type is deprecated and not supported for new chart creation via the API—modern ECharts chart types use identifiers like `echarts_timeseries_bar` instead [example](https://github.com/apache/superset/discussions/34750), [example](https://github.com/apache/superset/pull/34436). Here’s a minimal example of the JSON payload you’d use in a Python script to create or query a bar chart: ```python payload = { "slice_name": "My Bar Chart", "viz_type": "echarts_timeseries_bar", "datasource_id": 1, # your dataset/table ID "datasource_type": "table", "params": json.dumps({ "viz_type": "echarts_timeseries_bar", "metrics": ["count"], # or your metric "groupby": ["your_column"], # ...other chart options as needed }), } ``` There isn’t an API endpoint that lists all supported `viz_type` values. To discover the right parameters for a chart type, create a chart in the UI and inspect it with `GET /api/v1/chart/{id}`—the `params` field will show the config you need. You can also export dashboards or inspect the frontend plugin code for more details [reference](https://github.com/apache/superset/discussions/35978). Let me know if you want a full example for a specific use case! <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
