{"version":"1.0","type":"rich","title":"module 07 Q1","description":"This scatter plot visualizes a synthetic fitness dataset of 150 individuals, showing the relationship between hours of exercise per week (x-axis) and calories burned per week (y-axis). The points are colored by four activity-level clusters—Sprinters, Marathoners, Crossfitters, and Yoga Enthusiasts—using a D3 ordinal color scale. Built with D3 v7, the visualization uses `d3.select`, `d3.scaleLinear`, `d3.scaleOrdinal`, and the `join` pattern to render axes, circles, and an interactive tooltip. The data is procedurally generated with a seeded random function to create natural-looking cluster distributions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27de18d7c9994b8ca512a5f9dff75e97?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
