This fork of a D3.js v6 bar chart visualizes the relationship between COVID-19 confirmed cases and agriculture yield in Uttarakhand over time. It uses a dual-axis line chart with red and blue paths, and includes a legend. The code loads CSV data from a GitHub repository, parses dates with d3.timeParse, and renders the visualization as an SVG. The chart relies on d3.scaleTime and d3.scaleLinear for axes, and d3.axisBottom, d3.axisLeft, and d3.axisRight for tick marks, with a responsive layout defined by margin and size variables.
