This example presents two stylized vertical bar charts that visualize financial data about open speculations. The first chart displays "weight" values, while the second shows "gain" (relative gain), with bars colored to distinguish positive (green) and negative (red) outcomes. Built with React and D3.v5, the charts use SVG rendering and scaleBand/scaleLinear for axes, with rotated labels and custom tick formatting enabling compact display. The data is loaded dynamically from a JSON URL using D3's `json` utility.
