This visualization displays the change in worker counts for various companies from 2014 INC data, using vertical bars colored in steel blue. Hovering over a bar turns it dark orange and triggers a tooltip showing the company name and worker difference. The chart is built with D3.js v7, using `d3.csv` for data loading, `d3.scaleBand` and `d3.scaleLinear` for axes, and SVG rects for bars, with tooltip interactivity controlled through mouse events and CSS opacity transitions.
