{"version":"1.0","type":"rich","title":"activity 6_Task 1 ","description":"This chart displays the population of 30 countries in 2020 using a horizontal bar chart, with country names on the y-axis and population values on the x-axis. Built with React and D3 v5, the visualization uses `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and SVG rectangles as marks with native tooltips. Data is loaded asynchronously from a CSV hosted on GitHub via `d3.csv` (not `d3.forceSimulation` or other graph APIs), and population values are preprocessed by multiplying the year-2020 column by 1000. The axes are custom components (`AxisBottom` and `AxisLeft`) using D3 ticks and formatting with `format('.2s')` to display values in billions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fc06de9bc4844c2ab12f05be3cee8d99?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
