{"version":"1.0","type":"rich","title":"Assignment 2 7A Tree graph","description":"This example shows a hierarchical tree graph with a root node \"Srinivas\" branching into four internal nodes, each with two leaf nodes. The visualization encodes data properties through visual channels: node circles use radius for the value attribute, fill color from the level field, and stroke color from the type field. Links between nodes are colored based on the parent node's level. The code implements this using D3 v5's tree layout (`d3.tree`) and hierarchy function, rendering nodes and curved paths as SVG elements with data-driven styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7485676dece04efa99a0714f86181874?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
