{"version":"1.0","type":"rich","title":"Activity 7 Tutorial 2","description":"This visualization shows population growth over time for the first five countries in a CSV dataset, displaying semi-transparent overlapping area charts for each country. The code loads data via `d3.csv`, parses population values across nine census years, and uses `d3.scalePoint` for the x-axis and `d3.scaleLinear` for the y-axis. It generates areas with `d3.area()`, colors them via `d3.schemeCategory10`, and renders with SVG paths, axes, and text labels. The chart includes a title, axis labels, and country labels positioned near each area’s final value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/94a5252eb5e44501b3748050e52a657d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
