{"version":"1.0","type":"rich","title":"hw8_again","description":"This example shows a Sankey diagram of car evaluation data, displaying proportional relationships between attributes like buying price, maintenance cost, doors, persons, luggage boot, and safety. The diagram uses a React-based D3 v4 implementation with the custom `d3.sankey` layout, where nodes can be dragged vertically within their columns to explore connections. The code reads a CSV dataset from a remote URL, calculates ratio-based link values between attribute pairs, and renders the visualization as an SVG with draggable nodes and hover tooltips showing node names and values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f497d53bed384f70a486cb8c91905791?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
