This example presents a responsive bar chart that visualizes population estimates for the top 10 countries by total population, using data from the UN Population Estimates 2024 dataset. The chart displays the population values in thousands for each country, with bars rendered on a canvas that includes a light gray inner rectangle and labeled axes. The implementation leverages D3.js APIs including `scaleBand`, `scaleLinear`, and `axisLeft`, along with the `@curran/responsive-axes` library to handle dynamic resizing. The code also utilizes `observeResize` from `@curran/responsive-axes` to adapt the chart dimensions to its container.
