Basic Bar Chart - Country Population
✓ Published1🌍 Public
This example shows a horizontal bar chart comparing the populations of ten countries, using a static SVG rendering with D3 v5. It loads data from a CSV file and maps each country’s population to a bar’s width via a linear scale, while a band scale positions countries along the y-axis. The code explicitly uses d3.csv, d3.scaleLinear, d3.scaleBand, and d3.axisLeft/axisBottom to construct the visualization. Bars are drawn as SVG rect elements, and axes are appended to a translated group, with a steelblue fill applied via CSS.
