As presented by [Wallinger et al.](https://arxiv.org/abs/2108.05467) and implemented for [JS](https://github.com/schochastics/edgebundle/commit/77af8bbe7202f668100f19a0207bb5d8016d04b4) and [R](https://github.com/mwallinger-tu/edge-path-bundling), would be nice to add a Python implementation of this improved edge bundling algorithm. ![image](https://user-images.githubusercontent.com/1695496/139750805-578cfedb-3d54-4fac-a8f5-8e5cfdfdd2bd.png)

It would be nice if it were easy to use Datashader as a [WMS](https://en.wikipedia.org/wiki/Web_Map_Service) server, dynamically running an aggregation and returning the result using the WMS protocol.

Data often starts out as NumPy arrays rather than Dask or Pandas dataframes, and it could be useful to work directly with such arrays (see #283). I briefly investigated how...

InteractiveImage does not currently work in JupyterLab: ![image](https://cloud.githubusercontent.com/assets/1695496/18913788/737e1db6-854f-11e6-94de-ebe6af80b3cf.png) We will need to investigate.

It would be great to have a reduction operator that computes a median. Here's a first pass: https://gist.github.com/kidpixo/16e76ac201375e4d3fb4bf89b8a9b6ad (Notes adapted from @jcrist:) Unfortunately, median is one of the few reductions...

[From @pzwang, 11/2015] Could basically look like this, with some graphical controls to change aspects of the animation. Really, parameters of the animation are just additional variables for the transfer...

For floating-point aggregate values, datashader uses NaN to indicate masked bins, i.e. bins with no data. Integers have no agreed-upon NaN value, and for now the `interpolate` and `colorize` methods...

For eq_hist, there are two useful ways to label the colormap ranges: as numeric values, and as percentiles. Percentiles should be linear across the visible range (if histogram equalization has...

The examples on the [holoviews.org](http://holoviews.org) homepage show how to use a histogram as a color key, which would be really useful for datashader since we are working with very non-uniformly...

It would be helpful to provide tools or at least examples for analyzing how stable a visual representation is, across some parameter values. For instance, when the binning resolution of...
