<!-- Please fill in the following information to help us review your PR more efficiently. --> ## Brief Information Multiple level drill down support for the [universalTransition](https://echarts.apache.org/en/option.html#series-bar.universalTransition) feature. This pull request is in the type of: - [x] bug fixing - [x] new feature - [ ] others ### What does this PR do? In this PR, a new property `childGroupId` [comes up](https://github.com/apache/echarts/issues/16152#issuecomment-1207182380) and together with `groupId`, they can build multiple "parent-child" relationships between options. It is necessary to decide whether `groupId` or `childGroupId` is used as key in the keyGetter funtion to make sure that universalTransition animation does right, so I figured out a way to handle this, please see the block comments in code (that "direction" part). A test html file is added to illustrate how to use `childGroupId` with `groupId` to implement the effect of multiple level down drill. Also fixed #17309 by the way, so #17559 can be closed if this PR is merged (I just cherry picked the commit in that PR to this branch). ### Fixed issues - #16152 - #17309 ## Details ### Before: What was the problem? <!-- DESCRIBE THE BUG OR REQUIREMENT HERE. --> <!-- ADD SCREENSHOT HERE IF APPLICABLE. --> Only 1 level drill down is allowed. ### After: How does it behave after the fixing? <!-- THE RESULT AFTER FIXING AND A SIMPLE EXPLANATION ABOUT HOW IT IS FIXED. --> <!-- ADD SCREENSHOT HERE IF APPLICABLE. --> Multiple level drill down is allowed: https://user-images.githubusercontent.com/32434520/188168209-b26f4e0e-65de-4c96-9c9b-52c6d6e10c39.mov ## Document Info One of the following should be checked. - [ ] This PR doesn't relate to document changes - [x] The document should be updated later - [ ] The document changes have been made in apache/echarts-doc#xxx ## Misc ### ZRender Changes - [ ] This PR depends on ZRender changes (ecomfe/zrender#xxx). ### Related test cases or examples to use the new APIs N.A. ## Others ### Merging options - [x] Please squash the commits into a single one when merging. ### Other information This small feature is an OPSS2022 [task](https://summer-ospp.ac.cn/#/org/prodetail/22ffc0289), thank you guys from echarts core team to give me so much help when I was developing it! -- This is an automated message from the Apache Git Service.
