The last part of the series with parts of the report I made for the Multimedia Journalism module, this time about data visualization.
Experiments in Data Visualization
I did some research about newspaper brand values and online traffic of Portuguese news websites, and I came across with the monthly traffic report for all of them. My goal was to understand the relative and proportional position of each one, regarding visits, page views, and how those two values relate to each other. The data I got also has portals, specialized websites, and entertainment magazines so it has a broad range of themes (all charts are available live here – http://is.gd/aZLXs)
First of all I wanted to have a general overview of the size of each one when it comes to space within the Portuguese online universe, so I went for a tree map. The view wasn’t clear enough, so I tried a different approach, using a bubble chart, highlighting just the focus of my research, which were specifically newspapers. It was a better option, and I could have done things even more interesting if I added the paper circulation data. One of the conclusions that I would have found was that best selling newspapers don’t necessarily do equally well online.
But the real risk when connecting data is to draw wrong conclusions from fact. So these are the most successful websites, looking at these data sets right? Well, maybe not. What if we try to understand who are better at engaging the audience and get more page views per visit?
The idea that I got is that we can use data visualization to find a perspective on the subject and that will lead us to a better understanding of what were just numbers on a paper.
