Making a Bar Chart
This bar chart displays the population of the top 10 most populous countries, based on 2018 estimates from the United Nations World Population Prospects 2017. The chart uses D3 v5 with an SVG rendering, employing `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the categorical y-axis, with customized axes via `d3.axisBottom` and `d3.axisLeft`. Data is loaded from a CSV file and formatted using `d3.format`, with the x-axis label and title added as SVG text elements.
