Changelog:Supports Reverse Direction (Four Areas: nodeEnter, nodeUpdate, nodeExit, diagonal)
Popup window: Compatible with IE10, but apparently not compatible with Edge. I haven't tested it thoroughly, and my computer does not have IE. (Replace offsetX/offsetY with layerX/layerY.)
Clicking a node displays the popup at the node's position without losing focus. (The last two lines in the click event are commented out.)
You can contact me via QQ: 279470138. I have only worked with this d3.js tree chart, which uses v3. Regarding compatibility issues, I haven't looked into them.
The local JSON file is used. The API integration code was not organized, so it was not uploaded.
