{"version":"1.0","type":"rich","title":"Activity 6 Q2","description":"This example visualizes survival outcomes on the Titanic by passenger class using two overlaid area charts. It loads the Titanic dataset from a CSV URL and filters the data into survived and non-survived groups, then uses `d3.rollup` to count occurrences by class. The SVG rendering employs `d3.scaleBand`, `d3.scaleLinear`, `d3.area`, and `d3.axisBottom`/`d3.axisLeft` to draw the paths, axes, and a color-coded legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/61519b38f2254e188086e308c3dd81cf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
