This scatter plot visualizes the populations of the ten most populous countries, with each country positioned along the y-axis and its population (in thousands) along the x-axis. The visualization uses D3 v5 APIs such as `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom` to construct the plot, and renders as an SVG. Data is loaded from a CSV file via D3's `csv` function, with circle marks colored steelblue and grid lines styled via CSS.
