This example shows a bar chart of sales amounts by country, with two bars displaying the dataset values from the USA, UK, and Canada. The visualization uses an SVG rendering approach with D3.js v7, employing `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` to create the corresponding axes. Bar rectangles are appended to the SVG container with their width determined by the scale’s bandwidth and their height proportional to the sales values.
