This scatterplot displays the relationship between IQ scores and internet speed in megabytes per second across 53 countries, with each country represented as a red circle at 50% opacity. The visualization uses D3 v5 to load data from a CSV file and render an SVG chart with linear scales for both axes. Grid lines created through `axisBottom` and `axisLeft` with negative tick sizes provide reference points, while axis labels clarify the variables being compared.
