treemap zoom limitation

Steps to Reproduce

https://echarts.apache.org/examples/en/editor.html?c=treemap-disk open this example and zoom out until nothing to show remains.

Current Behavior

hello and thank you for this magnificent library. I am unsure if this is a bug or requesting a new feature. the problem is that zooming in treemap doesn't have any limitation, so if a user zooms out too much, the chart becomes so tiny that it becomes the size of a point and finally will disappear, so the user should reopen the page to see the chart again.

Expected Behavior

I think we need configs to define the min and max valid zoom range and prevent zooming out more.

Environment

- OS: Ubuntu
- Browser: chrome 99
- Framework: react

Any additional comments?

I'm sorry to close this issue for it lacks the necessary title. Please provide a descriptive and as concise as possible title to describe your problems or requests and then the maintainers or I will reopen this issue.

Every good bug report or feature request starts with a title. Your issue title is a critical element as it's the first thing maintainers see.

A good issue title makes it easier for maintainers to understand what the issue is, easily locate it, and know what steps they'll need to take to fix it.

Moreover, it's better to include keywords, as this makes it easier to find the issue self and similar issues in searches.
