PX color by timedelta

[harahu]

When you domain is time series data, you sooner or later have to plot data of the Timedelta type. It would be nice to be able to understand what I am looking at when plotting, and coloring by, such data, which is hard when it is interpreted as an int in both hover text and color bar tick text.

Similar to #2450, but covering the timedelta data type, rather than datetime.

See also #799 and #801 for similar requests for the x and y axes.

Hello!

Thanks for your enthusiasm and for linking up all these datetime/timedelta-related issues :)

In principle we would love to support all of the cases you're describing, but right now none of them are on the Plotly team's roadmap. This means that the ways forward would be for someone from the community to do the implementation (mostly in Plotly.js) or for an organization to sponsor the work to push it up higher on the Plotly team's roadmap.

If you're able to do the implementation work or know someone who can, please get in touch! And if you work for an organization with a software budget, please consider sponsorship :)

@nicolaskruchten Will look into your suggested options. Do you have a ballpark estimate for sponsorship cost for something like the collection of these issues?
