This example renders a horizontal bar chart of 2010 population data for 20 countries, sourced from a CSV file hosted as a GitHub gist. The visualization is built with React and rendered as SVG, using D3 v5 functions such as `scaleBand`, `scaleLinear`, `max`, and `format` for data handling and scaling. Interactive tooltips display the population value for each bar, and the axes are drawn with custom components, with blue tick lines and light green marks.
