Making a Bar Chart - 072019
This bar chart displays population figures for ten countries, sourced from a CSV file where values are multiplied by 1,000 for readability. Using D3 v5’s `scaleLinear` and `scaleBand`, it maps population to horizontal bar widths and country names to vertical bands. The SVG chart includes `axisLeft` and `axisBottom` for labeled axes, with bars rendered as `rect` elements. The code imports specific D3 modules—`select`, `csv`, `max`, and axis/scale functions—and applies a steelblue fill via CSS.
