Data Storytelling
Visualize Data with a Heat Map
A D3-powered heat map charting monthly global land-surface temperatures from 1753 to 2015. Hover or focus any cell to inspect temperature variance against the historical baseline.
Data Visualization Projects
The heat map ingests the NASA temperature dataset via fetch, then leans on D3 band scales and threshold color ramps to position each month while encoding variance with an accessible tooltip and keyboard support.
Trigger the refresh-and-fetch control to repeat the AJAX workflow, recompute the legend, and redraw the grid so the visualization reflects the latest payload end-to-end.
