D3 is a chart class library based on JS and SVG, which has rich examples. I wanted to find a ready-made one to express the system status and network traffic transmission. Unfortunately, this one that is the closest to the requirement only supports the tree structure using d3.js to visualise hierarchical classification, so I made some changes myself. effect: Features: Supports both tree and mesh Struct
