Barchart step 1
This example displays a horizontal bar chart of the top 10 countries by population for 2020, using data loaded from a CSV file via `d3.csv`. React state manages the asynchronous data fetching, and once loaded, `d3.scaleBand` and `d3.scaleLinear` position the bars within an SVG. The bars are rendered as `<rect>` elements, with the chart lacking axes or labels at this initial step.
AI-generated descriptionA program that loads in some data about CSS named colors using d3 utilities, and uses React state to keep track of the data.
