This scatter plot displays city areas in square meters along the x-axis with city names on the y-axis, using a linear scale for area and a point scale for cities. The visualization renders purple circles with hover effects, and includes axis tick lines and labels for readability. The code uses D3 v5 modules including `scaleLinear`, `scalePoint`, `axisLeft`, `axisBottom`, and `csv` to load and parse the data from a CSV file, with the chart drawn as an SVG.
