{"version":"1.0","type":"rich","title":"Activity6_population ","description":"This example visualizes the top 20 countries by population in 2010 using a horizontal bar chart. The code loads CSV data from a GitHub gist via `d3.csv`, sorts it in descending order, and renders SVG bars with `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, while tick labels are formatted in millions. The chart includes axis labels and uses steelblue bars, demonstrating D3 v7’s data binding and SVG rendering capabilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f514a1d9f2aa4658a1a22721f79383ed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
