- Abstract
As the frequency and intensity of climate anomalies continues to rise, it is important to have tools to quickly visualize their impact. On January 31st, 2019, Midwesterners in the US woke up to temperatures as low as -30 degrees Fahrenheit. The National Climatic Data Center provides accurate information that we can use to analyze this event.
This nearest-neighbor (Voronoi) diagram with cells shaded to represent temperatures is an example of one such tool. The shaded regions you see partition the country into regions based on which weather station is closest. While methods exist that allow for smoother shading over geographic regions, Voronoi diagrams allow you to see the data recorded at each distinct weather station. While this quality is shared with scatter plots, the Voronoi cells fill the white space left by scatter plots to ease visual comparisons.
