This fork shows a horizontal bar chart of the top 10 most populous countries, using data from the year 2019. The visualization renders to SVG via React and uses D3's `scaleBand` and `scaleLinear` to map country names and population values to coordinates. Axes and grid lines are drawn using `axisLeft`, `axisBottom`, and `ticks()`. The dataset is loaded from a CSV URL, though the URL is empty in the code.
