{"version":"1.0","type":"rich","title":"Data Visualization Homework 8: Sankey Diagram","description":"This visualization is a Sankey diagram that depicts the flow of car attributes—buying price, maintenance cost, number of doors, person capacity, luggage boot size, and safety—toward a final evaluation of acceptability. The diagram uses nodes for each attribute-value combination and weighted links to show the sequential relationships between them. The code builds the graph by parsing a CSV file and then uses a custom `d3.sankey()` layout algorithm to position nodes and links, rendering the final output as SVG. Interactive dropdown menus allow the user to select which columns to compare.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/57faef9aa287494f96826200f59755e6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
