This bar chart displays the population of the top 10 most populous countries, with values sourced from the World Population Prospect 2017 via a local CSV file. Using D3 v5’s `csv`, `scaleLinear`, and `scaleBand`, it maps population counts to bar widths and country names to vertical bands. The chart renders as an SVG with gridlines from `axisBottom`, formatted tick labels via `format`, and a title and axis label. Data values are multiplied by 1,000 in the loading callback.
