This visualization uses a bar chart to display the population counts of the largest 5 countries, with bars sorted by population size and labeled with country names. It is built with Vega-Lite API, which generates the chart using D3.js for rendering. Population data is loaded from a CSV file via D3’s `csv` function, and the tooltip shows the numeric population value. The chart is configured with customized axis styles and dark text for better readability, using the vega-tooltip handler for interactive display.
