{"version":"1.0","type":"rich","title":"My Knowledge Graph","description":"A network diagram maps related data-processing terms as colored nodes grouped into five hierarchical levels, with directed arrows showing learning dependencies between concepts. Built with D3 v5 and rendered as SVG, the visualization uses `d3.scaleOrdinal` to assign categorical colors and custom SVG markers for arrowheads. Links are drawn as simple lines with tooltips, while node positions are fixed by the dataset rather than a force simulation, presenting a static knowledge graph.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35ca80b381294217bae5a7415008a0f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
