missing equivalent for `mesa.visualization.PieChartModule`

as of 92366f9b4d61c66cad7b910880c33cb4c89024ef, `forest_fire` is using `mesa~=2.0` and `PieChartModule`

`mesa>=3.0` does not have `PieChartModule` or equivalent so an update of that example cannot include it

Start by locating the forest_fire example and reviewing its use of mesa.visualization.PieChartModule at commit 92366f9b4d61c66cad7b910880c33cb4c89024ef. Check the Mesa 3.0 visualization entry points for a supported equivalent, then verify the example runs on mesa>=3.0 and still presents the fire visualization without PieChartModule.
