Satellites in Orbit

2019 Week 24 Viz

DataViz Approach

For this viz, I wanted to look at the satellites distribution in space. The easiest way to visualize this was to use the distance away from Earth for each satellite and plot that in what looks like circular orbits. To force the points to space, I used what is effectively a radial jitter with the INDEX() function with a modulus. I then modified the calc to only plot over 180 degrees in the interest of space.

I then pulled out some key points that I found in the data - the number of satellites, the large percentage in two very specific distances, the lifespan of satellites and the geographic ownership. Each metric has an interactive element - whether its set actions to highlight the distribution in the main viz, or viz in tooltips. Really happy with the overall result!

We'd really love to see what you can do with this week's dataset! Download the data and see what you can visualize. Create your viz and post your work to Tableau Public and Twitter with the hashtag #ThrowbackDataThursday, tagging @TThrowbackThurs. We're really looking forward to seeing what the Tableau Community can come up with!
