{"version":"1.0","type":"rich","title":"Fork of Activity7:Question:2","description":"This area chart shows total app usage hours aggregated across five age groups, from under 20 to 50+, using a synthetic dataset of 49 users with age and usage values. The visualization groups the data with `d3.group`, sums usage per group with `d3.sum`, and renders the result as a filled path using the `d3.area` generator. The SVG employs `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and both axes via `d3.axisBottom` and `d3.axisLeft`, with labels for age groups and usage hours.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9d28273bb5c64d7c89c3c7e68956b11c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
