For this third and last Tableau #IronViz qualification round (follow the link and find my dataviz, if you want to vote for me!), I decided to build something using this cool dataset: a publicly available csv with ice extent in the northern hemisphere by region, updated daily.
As for the visualization, I chose to build a radial chart, because I had already built one focusing on the North Pole, and I quite liked the result. In this chart, each point is a day and each ‘circle’ is a year, while the ice extent is encoded in the distance from the center.
Using this dashboard, it is possible to get two information at a glance:
- The different seasonalities of the regions, that draw totally different shapes;
- The effect of climate change on the ice extent of different regions.
