New chart type - Tree Map

Is it possible to add a new chart type for tree maps? Various tiling algorithm implementations are already available for java/python. The “performance → securities” section of PP already has enough data to produce tens of useful tree maps. One can copy paste this to google docs and create a tree map there with a simple click:

a- Simplest implementation (single tree - one ancestor i.e: stock):
For a starter I’d like to see an allocation of all assets by size (single tree) colour coded by daily gains. Min, max and mid levels should be auto calculated, but there has to be an option to manually override for sane colour coding purposes (i.e 3% max, 0 mid, -4% min)

b- Low complexity, configurable data (single tree - one ancestor i.e: stock):
But I think once the tiling algorithm is implemented, it’d be trivial to change data source for “label”, “source”, “colour” and “hint” configuration options.
So if we wanted to recreate option a with this configuration:
label: Instrument name
source: market value
colour: Daily delta %
hint: Daily delta %
or another useful option:
label: Instrument name
source: absolute performance
colour: TTWROR %
hint: TTWROR %

c- Complex implementation (multi tree, multiple parents often nested)
In addition to data sources, a tree-map can be multi level. (Taxonomies?)

What do you think this symbol stands for?

I was thinking an option to add a chart to potentially a dashboard.

But fine I’ll play. I’m happy if what I’ve described is possible anywhere.

Can you please show me an implementation of any of the examples I’ve detailed. The taxonomy page as it is now, is rather useless, but I might be missing some hidden configuration somewhere.

No, because

that makes no sense (to me).

So it is currently possible but you don’t want to show because “it makes no sense”?

There is literally a screenshot of what it means in the original post… It is also the most common usage of treemap that you can see in all sorts of finance sites/news etc.

edit: pasting the first few results from “stock treemap today” google search result:

For taxonomies, you can create such charts:

Those are based on the data you provided.
