This bar chart visualizes the most loved programming languages from the 2018 Stack Overflow survey. It uses D3.js v5 with SVG rendering to display the percentage values for each language. The chart includes horizontal grid lines and value labels. Interactive animations occur on mouseenter, which highlights the selected bar, draws a dashed limit line, and displays divergence percentages showing how other languages compare to the selected one. The text labels, axes, and title are all implemented using D3’s scale and axis APIs.
