d3 js
This bar chart displays the populations of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects 2017. It shows a horizontal bar for each country, with the population value scaled linearly along the x-axis. The visualization uses D3 v5 APIs including `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the axes, while customizing tick formats to abbreviate large numbers and removing axis domain lines. Bars are rendered as SVG rectangles, with data loaded from a local CSV file. The code also demonstrates styling through an external CSS file.
