This bar chart visualizes the population of a region from 1950 to 2020, with population values multiplied by 1,000 and displayed on a linear scale. The chart uses horizontal bars, with years on the y-axis and population on the x-axis, rendered as SVG rectangles. The implementation leverages d3.v5 APIs including `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, and loads data from a CSV file.
