{"version":"1.0","type":"rich","title":"D3.js challenging - Level 1","description":"This example visualizes daily temperature records in a calendar-style heatmap, with the x-axis representing years and the y-axis representing months. Each cell encodes temperature values through color, and the visualization includes axis labels, gridlines, and a legend for color mapping. Built with D3.js v7, it uses `d3.scaleTime` for both axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and reads data from a CSV file. The code includes placeholder logic for rendering maximum and minimum temperatures and tooltip functionality, though those interactions are not fully implemented in the visible source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/235f65ca44ea4ff0bdfce12aa9db40ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
