Data can be portrayed in
various types of ways such as writing out sentences about your data, pictures of data, bar graphs, etc., but a very efficient way of doing this is by using data visualization. This method is a way to look at a chunk of data in a way where you don't have to read much, but just look at it and get a pretty good sense of what is it telling you. The main way of doing this is usually by a graph, chart, table, etc. to portray the data you have collected.
One specific type of visualization I looked at was called tree mapping. This was an interesting way of portraying information to people because it uses different sizes of shapes such as squares or circles to show how much more or less one thing is compared to another. For instance, one piece of visualization that used tree mapping was one where it showed popular fake news throughout the years 2017-2018. The bigger the square was, the more times that news was viewed or spread.

Another type of tree map I viewed that was interesting was one about the amount of breaches and hacks that happened in big companies and organizations throughout the last few years. These include some pretty
popular ones such as Facebook, Twitter, Uber, Apple and more. This tree map is a bit different than the usual because of the use of circles all around each other rather than squares all lined up perfectly together. In my opinion, this doesn't make the visualization easier or harder to look at, but just a different, interesting way of showing collected data. With all of these different sized circles shown, you can also hold your mouse over it to give the user a brief description of what happened with the hacks and breaches. Below are a couple of screenshots I took of the tree map I described. The one of the left just shows a portion of it, and on the right side it shows an example of a brief description about Facebook and the breaches it has had in 2019.
