This bar chart shows the estimated 2019 population for the top ten most populous U.S. states, ordered by state name on the vertical axis and population magnitude on the horizontal axis. The visualization uses D3 v5 with an SVG rendering, employing `scaleLinear` for the population axis, `scaleBand` for the state categories, and `axisBottom` with tick formatting to display abbreviations like “B” for billions. Data comes from a CSV file containing state population estimates and geographic coordinates.
