Human Capital Index Horizontal Bar Chart
This horizontal bar chart displays the Human Capital Index for 56 countries, using data from the World Bank via a CSV file. The chart sorts countries by HCI value in descending order, with each bar’s length representing the index and a numeric label showing the rounded value. Built with D3 v7, the visualization uses `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and SVG rendering with `axisLeft` and `axisBottom` to generate clean, tick-free axes. The bars are colored lightseagreen, and the data is loaded and parsed asynchronously using `csv()`.
