This network visualization displays the connections within a Data & AI ecosystem, arranging nodes in a fixed circular layout. Node colors encode group membership using a d3.scaleOrdinal with ten categorical colors, while links depict relationships between entities. The example loads two external CSV files via Promise.all and d3.csv, then manually positions nodes using trigonometric calculations rather than d3.forceSimulation. Circles and labels are rendered as SVG elements, with each node circle including a tooltip title showing the node’s id.
