This example visualizes quarterly financial ratios, displaying asset turnover as a bar chart where each bar is a sequence of quarterly dates, with gross margin and net income to revenue ratios appearing as red dots in a scatter plot. The controls allow filtering by company name and resetting zoom. The visualization uses D3.js v7 with SVG rendering and axes, and it includes zoom behaviors and hover tooltips for interaction. Data comes from a CSV file hosted on GitHub Gist, and the code is implemented in React.
