{"version":"1.0","type":"rich","title":"Chart 4","description":"This heat map compares monthly COVID-19 confirmed cases against agricultural yield, with the x-axis showing months and the y-axis two categories: \"Yield\" and \"Confirmed.\" The color encoding uses the D3 sequential Inferno scale (`d3.interpolateInferno`) to map numeric values. Built with D3 v6 and SVG, the chart loads data from a remote CSV using `d3.csv`, applies band scales (`d3.scaleBand`) for positioning, and includes axes, a legend, and mouseover tooltips to display exact month, yield, and case numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/71a8cbebec6049a2ad5d32e986efd7eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
