This example demonstrates the initial steps of building a bar chart with D3 version 7, though the visible code only loads and logs a CSV dataset of country populations using d3.csv. The dataset includes ten countries and their population figures, and the code selects an SVG element using d3.select, then sets up width and height variables from its attributes. The page’s body uses an extremely large font size, though no chart rendering or bar drawing logic is shown, as the example focuses on data loading and basic D3 setup for a tutorial video.
