With my banking background, I am fascinated by cryptocurrency. I discovered this comparison between Visa and PayPal and cryptocurrencies for processing transactions per second. Before I share my visualization, I want to share my observations about this visualization.
As I set out to reviz this chart, there were a few items that were top priority for me; changing the chart type to one that is more effective (in my opinion), changing the color scheme, and modifying the label use.
I found this image online and thought it had a great color scheme with the dark background and the light blue/teal that makes the individual images pop, which is what I wanted to carry over to the visualization.
The following visualizations provide a focus on the data. The first provides a focus on the comparison whereas the second provides a total to really show how few cryptocurrency transactions are processed per second compared to VISA. Additionally, the color scheme of the original visualization felt very bubble gummy to me and the shine on the bubbles is not an effective way to visualize data as it interferes with the readers' ability to comprehend the message the data is telling.
The above is an example of data visualization, whereas the following leans more toward visual analytics because of the conclusion on top of the pie chart. There are a lot of mixed feelings about pie charts. Some people despise them, some people love them. For me, I'm a believer of the best chart type for the data. In the example below, I believe a pie chart is an appropriate chart to show the relationship between the volume of cryptocurrencies and traditional payments. Additionally, by reading the title of the pie chart, one can understand that the bigger volume is related to traditional (and primarily VISA).
Project revizit complete! The visualization was really for me (though I did contribute to the monthly Storytelling with Data Challenge), and I am pleased with the first and second iterations.
