Research direction

Start by examining the listed Plotly Express trace-type functions and the existing 2D-cartesian facet behavior using facet_row, facet_col, and facet_col_wrap. Determine how facet support is represented across scatter_3d, ternary, polar, mapbox, matrix, coordinate, pie, sunburst, treemap, and funnel-area functions. Done means the requested facet parameters work consistently for the listed trace types, with coverage for their behavior.

Description

enhancement feature P3 size: 3

Currently, several Plotly Express trace types do not support the facet parameter:

This means scatter_3d, line_3d, scatter_ternary, line_ternary, scatter_polar, line_polar, bar_polar, scatter_mapbox, choropleth_mapbox, density_mapbox, line_mapbox, scatter_matrix, parallel_coordinates, parallel_categories, pie, sunburst, treetop, funnel_area do not support facets.

It'd be nice to add this parameter!
