Description

Is your feature request related to a problem? Please describe. When I use 3d Scatter chart, I need to customize the opts.markercolor which indicate the weights for different points. For instance, the darker of the points, the higher of the weight. However, the border of the points, which always assigned a darker color makes the visual evaluation harder.

So I'm wondering if there is any api or feature in the future provide the ability to change the marker edge width and color like what Plot.ly did.

Describe the solution you'd like Add more configurations in opts. like :

        self.vis.scatter(
            X=X,
            Y=Y,
            env=env,
            win=legend,
            opts=dict(
                markersize=2,
                markercolor=color_map,
                *markeredgewidth=0*
                name=legend,
                title=legend
            )
        )

Research direction
The issue requests adding marker edge width and color options to the 3D scatter plot in visdom. To implement, locate the scatter function in the visdom source code, likely in `visdom/plots.py` or similar. The function currently accepts opts like `markersize` and `markercolor`. Add new opts `markeredgewidth` and `markeredgecolor` and pass them to the underlying Plotly trace (since visdom uses Plotly). Ensure these options are documented in the docstring and reflected in the frontend. Check existing tests for scatter to add test cases. No linked PRs or comments indicate prior work, so this is a fresh feature to implement.
