Add Custom Marker Symbols for Scatter Trace

Hi all, really liking this framework so far. One feature that would be great to have would be the ability to add custom marker symbols to the scatter trace. It looks like I'm not the first person to be in need of this: https://community.plotly.com/t/i-want-to-use-custom-icon-for-the-scatter-markers-how-to-do-it/6644

I'm currently trying to overlay 2 of the existing symbols on top of one another to get a square with the 'Y' symbol inside. I can achieve this within the plot window easily enough by using two separate scatter traces, one with each symbol. Unfortunately there doesn't seem to be a way to make this look right in the legend. If I could instead use a single trace that would solve the legend issue, either by stacking shapes or more generally accessing the SVG syntax that's already used behind the scenes to render these symbols.

Any thoughts on whether this is feasible?

ファイルやテストの名前は指定されていません。まず、散布図マーカーのシンボルと凡例エントリがどのように表現されているかを追跡し、既存の SVG ベースのシンボルで 1 つの trace 内の合成またはカスタムシンボルをサポートできるかどうかに焦点を当てます。完了条件は、カスタムマーカーが正しくレンダリングされ、対応する単一 trace の凡例エントリがそれと一致することです。
