Sunburst using Bokeh or Holoviews

HoloViews

Hello everyone.

I hope you are all healthy and good. I`m a student and new to Data visualization with Python so I want to apologies if I made a wrong post, or asking a stupid a question, or in a stupid way and maybe not at the right platform. Forgive me.

I want to make a small dashboard which consists of only an interactive Sunburst diagram and interactive and reactive Sankey Diagram. Sankey diagram should show the current data being shown in Sunburst diagram and if we change categories in Sunburst, it should also change Sankey diagram accordingly.

I want to use Panel and Bokeh, but I could not find Sunburst Diagram in Bokeh library. Only library I found which had Sunburst diagram is Plotly, but it seems complicated compared to Holoviews and Bokeh. And I also don`t want to use Dash, as with Panel and Holoviews, it would be easier to use other libraries like Datashader, GeoViews etc late if I want to.

Some of my questions are:

1) How can I use Sunburst Diagrams with Holoviews? Is it possible?

2) If this is not possible, then can I use Plotly Sunburst diagram in the panel and have all the interactivity and access, like click-data, hover-data etc in Panel without using Dash?

3) Is it possible to use Plotly as backend for Holoviews and have all the functionality for Sunburst diagram?

4) Is it going to be more complicated, and should I switch to Ploty with Dash and climb the steep learning curve once and that would be more optimal?

Thank you for any help/advice. Have nice a day.

Kind Regards,
Gibrail Hassan

Hello,
thanks for joining this community!

1) Sunburst diagram can be seen as:

For the polygons I find this implementation in matplotlib which is not interactive but may be easily converted to holoviews.

In matplotlib this is done in polar coordinates directly. Easier with:

ax = ax or plt.subplot(111, projection='polar')

I don’t know if polygons have projection capabilities. I saw that scatter plot do.

If not, I would simply convert polar to cartesian coordinates in previews matplotlib implementation and make polygones.

Thank you, Thomas!
I think the radial heatmap comes close to what I am looking for.
This is the sample picture that represents what I want to make using Holoviews.

There are some categories represented by Sunburst, and each category has some sub-categories.
Each sub-category has an ambition level from 1 to 4, or 1 to 5 (each level for sub-category represents 20% or 25% share). It should be able to expand into individual sub-categories too.
Do you think it is possible to make such an interactive sunburst diagram using any of PyViz tools? or Dash and Plotly would be suitable for it?
Panel with Bokeh and holoviews would have been perfect match for this task if there was support for Sunburst diagram either direct or with plotly backend.
It looks like I`ll have to climb the steep curve of Plotly and Dash for now.

Yes.
I think it is possible.

In your image, I see 8 categories when 24 hours in holoviews exemple.
I see 2 sub-categories by categories -> 8*2 =16 values should be set in Y array in exemple.

An exemple with your dataset would make things easier to help.

I try to adapt a sunburst with the echarts pane but it does not work, and there is not any error in console.

This is the expected sunburst. I rendered it with the pyecharts function and it works. When I try to implement in a panel Row or Column it shows nothing and there is no error in the console.

pn.extension('echarts')

pn.Row(c).show()

you can see that c object is an pyecharts object, which according to the docs is supported.

If I use the render_notebook methof of pyecharts it is possible to render it in the notebook. It should be nice to be able to integrate with the templates.

Hi @nghenzi and others

The problem with the sunburst is that Panel does not automatically understand which panel type to put pyecharts objects in. If you replace the last line with pn.pane.ECharts(c, height=1000, width=1000).servable() it works. Please note it’s also important to set the height and width.

I’ve contributed a fix here https://github.com/holoviz/panel/pull/1877. Unfortunately it introduces “flickr” when making ECharts depend on sliders.

FYI. @nghenzi
