Viz Remake: NASA’s Global Land-Temperature Index

This past week I saw this tweet from Elon Musk:

This led me to have a look at the data visualisations on NASA’s website, in particular, their viz of the global land-temperature index which reminded me a lot of all of the great work we saw for Makeover Monday week 20 - Global Warming is Spiraling Out of Control.

There’s so much to like about this visualisation. It has a great summary on the left with a massive number that is the centre piece of their story. Their intentional design of making the large number the focus make the line chart supplementary. The line chart is clear and simple, the legend is out of the way and the beacon on the end captures your attention.

The data is available right there below the viz so I downloaded it so that I could reproduce this in Tableau. I often attempt to recreate visualisations I like as a way to learn and practice. Because in the end, the only way to get better is to practice…A LOT!

I was able to reproduce everything bar the blinking dot on the end of the line. I also chose to fill in the circles on the grey line because I don’t care for the open circles. Lastly, I added a + to the beginning of the large callout number. I think that helps provide a quicker understanding of what the number means.
