{"version":"1.0","type":"rich","title":"Activity6_Tutorial1","description":"This example shows a horizontal bar chart of the top 30 countries by 2020 population, ranked from largest to smallest. The bars are rendered as SVG rectangles colored light green, with a linear x-axis scaled to the population values and a banded y-axis listing country names. The chart uses D3 version 7, specifically `d3.axisBottom` and `d3.axisLeft` for axes, `d3.scaleLinear` and `d3.scaleBand` for scaling, and loads data from a CSV file using `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/792686726ca640439f71c8cc58f0b13a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
