This work is a horizontal bar chart that displays the top 20 most populated countries in 2010, using population values in millions. The chart ranks countries from highest to lowest population, with bars encoded by length and colored pink. Hovering over a bar reveals the specific population value via a tooltip. The visualization is rendered using React and D3.v5, and it uses `scaleBand` and `scaleLinear` for axes, `format` for tick labels, and `csv` to load the dataset.
