{"version":"1.0","type":"rich","title":"activity6_tutorial1","description":"This horizontal bar chart displays the top 30 countries by population in 2020, using a lightgreen fill for each bar. The chart sorts countries along the y-axis with population values on the x-axis, formatted with a custom tick formatter that converts values to billions. Built with D3 v7 and SVG, the visualization leverages `d3.scaleLinear` and `d3.scaleBand` for positioning, while `d3.axisBottom` and `d3.axisLeft` render the axes. Data is loaded asynchronously from a CSV file via `d3.csv`, with the population column parsed as a number.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/806afeaa5d674295ad1a2cc82a701fce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
