Implemented with D3.js v3, it loads hierarchical JSON data from a local file and renders the tree as SVG, with nodes colored by type and directional links between them. The visualization includes zoom and drag functionality, as well as tooltips, and uses custom CSS classes to style the node rectangles and link paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f30025c47274853b1a008d1637cdef1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
