## Description
- Connect Pie Chart to the backend
- Update from the old design to the new design
- Switch seamlessly from/to other types of chart from the Pie Chart by
converting the configuration
Note: There are a couple things to implement before the pie chart is
ready to go live:
- Add a new setting on Bar, Line and Pie chart to hide and display
legends (toggle)
- Add data labels next to each slice

- Allow users to choose the date granularity of the x axis and the group
by of the y axis on a bar chart
- Display those options conditionally
- Store timezones in graphs: each graph has its own timezone, defaults
to the user timezone. There will be a picker in the v2 to choose the
timezone. For now the timezone is not used by the backend, but it will
be used in filters and in group by queries.
- Store first day of the week

### Summary
Split BAR into VERTICAL_BAR and HORIZONTAL_BAR as separate chart types.
### The Problem
Initially wanted a simple vertical/horizontal toggle for bar charts, but
ran into a GraphQL union type
constraint: union types can't have the same field name with different
nullability.
- Vertical bars need groupByFieldMetadataIdX as required (categories on
X)
- Horizontal bars need groupByFieldMetadataIdY as required (categories
on Y)
- GraphQL schema generation fails with this setup
### The Solution
Use semantic primaryAxis and secondaryAxis naming that's
orientation-agnostic:
- primaryAxisGroupByFieldMetadataId = main grouping field (e.g.,
"Company Name")
- secondaryAxisGroupByFieldMetadataId = optional secondary grouping
(e.g., "Stage")
These fields have consistent meaning regardless of orientation. The
visual mapping happens at the UI layer:
- Vertical bars: primary data renders on X-axis, secondary on Y-axis
- Horizontal bars: primary data renders on Y-axis, secondary on X-axis
Both chart types share the same DTO structure with consistent
nullability.
### What Changed
- Split GraphType.BAR → VERTICAL_BAR | HORIZONTAL_BAR
- Renamed fields: primaryAxisGroupByFieldMetadataId,
secondaryAxisGroupByFieldMetadataId (+ subfield
variants)
- useChartSettingsValues(): Maps semantic fields to setting values (no
swapping)
- getBarChartSettings(): Dynamically arranges settings panel based on
orientation
- transformGroupByDataToBarChartData(): Maps semantic fields to Nivo's
layout prop

This PR is the first part of the creation of the Chart editor.
https://github.com/user-attachments/assets/8b0af8ea-be41-4506-84cb-e40f5521cbf0
Done:
- Bar chart settings (except filters)
- Line chart settings (except filters)
In progress:
- Pie chart settings
- Number chart settings
- Gauge chart settings
Left to do:
- Loosen the backend validation to allow the user to save a partial
configuration, validate the graph configuration in the frontend and
display a error friendly message in the graph if the config is not
completed yet
- Implement the filter edition
- Finish the other graph types settings
