Re: [D] Boxplots No Aggregate [superset]

<!-- Greeting -->
Hi @vincent-reau! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the superset team.

Superset's boxplot visualization requires aggregation because it computes statistics like mean, median, quartiles, min, max, and outliers for each group using SQL queries that group and aggregate your data. This is why you see the error about needing to use your column in a GROUP BY clause or aggregate function—the boxplot chart expects grouped and aggregated data to calculate its distribution metrics, not raw values directly. There isn't a built-in way to display boxplots of raw (non-aggregated) values in Superset; aggregation is a core part of how boxplots are implemented in the platform [see source](https://github.com/apache/superset/blob/master/superset/utils/pandas_postprocessing/boxplot.py).
If you want to visualize raw scaled values without aggregation, you might consider using a different chart type, like a scatter plot or strip plot, which can show individual data points. Alternatively, you could export your data and use an external tool that supports raw-value boxplots. Superset does not currently support plugins or alternative chart types for boxplots without aggregation [see source](https://github.com/apache/superset/blob/master/superset-frontend/plugins/plugin-chart-echarts/src/BoxPlot/buildQuery.ts).
