This example visualizes a browsing history as an interactive Sankey diagram, mapping sequences of web searches and page visits as flows between nodes. Each node represents a search query or website, while links show transitions from one action to the next, with stroke width indicating the number of transitions. The diagram uses the d3.sankey layout to position nodes and compute link paths, with SVG rendering for nodes and links. Nodes are draggable via d3.drag, and colors are assigned using d3.scaleOrdinal. The underlying data comes from a JSON file containing node names and directed links, while a CSV file holds the actual browsing log details.
