This example demonstrates a fork of a fork of a blank canvas, presenting two distinct bar chart visualizations. The first chart renders a simple dataset with values 4, 8, 15, 16, 23, and 42 using D3 v7's `scaleLinear` and `select`/`selectAll`/`append` APIs to draw rectangles and text labels on an SVG canvas. The second chart uses the Chart.js library to display categorical vote counts in a bar format with semi-transparent background colors and border styling. Both charts are drawn to an HTML canvas element, with the page's styles defining a fixed, full-viewport layout.
