This bar chart visualizes lion populations across seven African countries, with population values from a CSV file and a title indicating the dataset's scope. It demonstrates custom axis styling: the y-axis removes its domain and tick lines, while the x-axis applies a tick format that abbreviates large numbers, using d3.axisBottom, d3.axisLeft, d3.scaleLinear, and d3.scaleBand. The SVG rendering includes a custom axis label and title, with tick text and lines styled via CSS.
