This example reconstructs a bar chart from memory, displaying the relative lengths of different candy bars using circles positioned along categorical and linear scales. The code loads data from a CSV file, then uses D3 v5 APIs including `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom` to render the SVG visualization. A title and custom styling via CSS complete the chart, which plots each bar’s length as a circle’s x-position on a numeric scale, with y-position determined by its name.
