{"version":"1.0","type":"rich","title":"Final Project","description":"This scatter plot displays insurance charges against patient age, with points colored by a user-selected attribute such as smoker status, sex, region, BMI category, or number of children. A legend updates dynamically, and linear regression lines are calculated for each color group to reveal trends. Built with React and D3.js (d3.v7), the visualization uses `d3.csv`, `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.axisBottom`/`d3.axisLeft` to render the chart from the `data.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/758f14b8770f4af6a08c54e60b9eff18?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
