This Year's Rainfall
Stanley's cumulative rainfall so far this year against its own record — the normal accumulation, and the wettest & driest years to date. The bright line is the running total; where it rides the band tells the story at a glance.
Stanley's entire daily record as one heatmap — each row a year, each cell a day, shaded by that day's rainfall. Dry spells read as dark blocks, wet seasons as brighter bands; the whole climate at a glance.
