10229428 opened a new issue #12312: What is the maximum number of nodes that the tree map can contain?
URL: https://github.com/apache/incubator-echarts/issues/12312
### Version
4.7.0
### Reproduction link
[https://jsfiddle.net/tianhen0527/c63wvfjr/](https://jsfiddle.net/tianhen0527/c63wvfjr/)
### Steps to reproduce
Use the data with about 30 nodes, the tree map can be displayed normally. But when I use the data with 700 nodes, the page crashed!
I have put the test data with 700 nodes in the buttom of https://jsfiddle.net/tianhen0527/c63wvfjr/
### What is expected?
The tree can be displayed normally.
### What is actually happening?
The page crashed! Exception occured in Console:
```
RangeError: Maximum call stack size exceeded
at run (editor.js?_v_=1584687926098:1)

@100pah
Thanks for your answer.
As you said, maybe it depends on the max stack size of the browser. But I can not ensure that the user ’s brower will be ok.
I use the `treemap` to show the histories for some operations. I have limited the number(or level) to 600, the excess will be deleted automatically.

I can not reproduce the "Maximum call stack size exceeded" error by the 700 nodes in the bottom of https://jsfiddle.net/tianhen0527/c63wvfjr/ in the latest Google Chrome.
But theoretically the error would be thrown if the data is too deep. Based on the current implementation,
it depends on the max stack size of the browser. The number in modern browsers would be bigger than 10k, but is legacy IE may be several thousand.
@10229428 Could I know what environment do you used?
Anyhow, consider that `tree` and `treemap` do not necessarily display all of the nodes, `tree` and `treemap` should
better be improved to raise the upper bound of the supported data levels.
