Description

At the moment the size of markers is in plot units, ie markers keep the same size when zooming in or out. It would be useful to have the possibility to have a marker size in data size, ie markers would get bigger on screen when zooming in.

Requested for example in the forum https://community.plotly.com/t/keeping-dot-size-fixed-on-scatterplot/39539.

The equivalent feature for 3D glyphs is documented in #4329

Research direction

Start by reading the behavior described here and compare it with the equivalent 3D glyph feature documented in issue #4329. Then locate the 2D marker rendering path and determine how marker size currently uses plot units; done means offering a data-unit size option whose on-screen size changes with zoom while existing sizing remains available.
