{"version":"1.0","type":"rich","title":"Assignment5","description":"This dashboard visualizes the relationship between market capitalization and revenue for 30 U.S. companies, with each dot representing a single firm. The interface allows switching between five chart versions that explore different encoding channels, from position-only to color and area variations. Built with D3 v7, the visualization uses `d3.csv` to load data from a GitHub gist, `d3.extent` for summary statistics, and SVG rendering for the scatter plot. The code also includes interactive navigation buttons that update the chart's visual encodings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/adcca118b28c4b37a94caaeb864ae79d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
