{"version":"1.0","type":"rich","title":"Activity6_Task1_Tutorial_Alt","description":"This horizontal bar chart displays the top 30 countries by 2020 population, using green bars to compare values across a blue-ticked axis. The visualization loads CSV data from a GitHub gist, parses the population column, and renders an SVG using D3 v7's `scaleLinear`, `scaleBand`, and `d3.axisBottom`/`axisLeft`. Custom ES6 modules (`Marks.js`, `AxisBottom.js`, `AxisLeft.js`) encapsulate the bar drawing and axis formatting, with tick labels formatted in compact notation (e.g., \"1.2B\").","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6f9a5f3a9584ffaac69c5ab38056583?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
