{"version":"1.0","type":"rich","title":"activity7 question2","description":"This example visualizes customer churn from a Telco dataset, showing the distribution of customer tenure (in months) split by churn status. Two overlapping area charts compare the counts of churned versus non-churned customers across tenure durations. The visualization loads data via `d3.csv`, preprocesses it using `d3.rollup`, and renders SVG areas with `d3.area`, scaled axes via `d3.scaleLinear`, and an ordinal color scale. A legend distinguishes the two categories, with labels applied directly to the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/01acc4c0d7f848feb1403fd282db1716?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
