{"version":"1.0","type":"rich","title":"directional_graph_wo_hierarchy","description":"A directed graph of 13 labeled nodes and 21 links shows a learning-path dependency structure, with nodes grouped into five color-coded categories. The layout is computed live using `d3.forceSimulation` with `forceX` and `forceY` forces to pull nodes toward predefined column positions per group, plus `forceLink` and `forceCollide`. SVG lines with `marker-end` arrowheads render the edges, and the data is imported from a JavaScript module.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2918a1bb6559424dae32a7fb92345e9e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
