Enable rendering of custom HTML

[davidhahnfb]

Is your feature request related to a problem? Please describe.

Currently, ReRun does not support rendering of custom HTML elements in its UI. There are some plotting utilities but they are not as robust and feature rich as dedicated libraries like plotly and supporting pre-existing custom visualization tools can be a large lift as it may necessitate re-write of the tool or more feature requests on the ReRun side.

Describe the solution you'd like

One way to enable plotly and custom visualization tooling is to use HTML as a common interface. Plotly for example already supports export into HTML elements. If ReRun can enable rendering of custom HTML, then any visualization library which enables output of its elements in HTML can be rendered.

Describe alternatives you've considered

One alternative which is already supported is to render visualizations into images and simply log an image to ReRun. However this severely limits interactive features for these visualization tools which is a strength of plotting libraries like plotly.
