This histogram visualizes the populations of the top 10 most populated countries as of 2018, sourced from a local CSV file. The chart uses SVG rectangles rendered via the D3.js library, with each bar’s height corresponding to the country’s population value (scaled by 1000). The code relies on `d3.select` and `d3.csv` to load and bind the data, while CSS styles the tick labels and lines. The visualization focuses on comparing population magnitudes across the listed nations.
