This is a bar chart visualization of the top 10 most populous countries, displayed without axes and using a deliberately simple design. It is built with React and D3 v5, rendering SVG elements through React components. The chart pulls data from the UN World Population Prospects 2019 dataset, scales the x-axis linearly with `d3.scaleLinear` and the y-axis with `d3.scaleBand`, and constructs the bars and axis labels using custom React functions.
