## 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

Issue -
- tooltip gets too long when groupby has too much data points
- we need max height on tooltips
- we need to be able to scroll inside the tooltip
- not possible if the tooltip is following the cursor (which library
enforces)
- its not easy to customize Nivo's own tooltip to make it work how we
want it
what we want -
- let the tooltip anchor to the bar in such a way -- that the top of the
bar aligns with the vertical middle of the tooltip
- add max height to the tooltip
what I did -
- use floating portal from floating-ui/react
- get the hover datum (ie hovered bars) dimensions on mouse enter to
render the tooltip
- anchor the tooltip at the calculated position
- floating-ui handles the basic things like flipping/offset/shift
- clear the states as required

### 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 is the third PR from the split of
https://github.com/twentyhq/twenty/pull/14458 - refactoring only the
PieChart widget.
Plus small performance improvements on already refactored widgets
