This example visualizes the Vijayanagara family lineage as an animated, color-coded tree diagram, showing hierarchical generations from the founding ruler downward through descendants. The visualization uses D3.js version 3, specifically the `d3.layout.tree` for node positioning and `d3.svg.diagonal` for link paths. Each node is rendered as a circle with a fill color indicating generation level (black for root, blue for first generation, red for second, green for third). The tree expands with a 1000-millisecond transition, using node data updates to shift positions and reveal new descendants dynamically.
