I found this interactive timeline that talks about the largest data breaches in the world more than 30,000 records. There are many good things about this visualization and many negative things also. To start with the negative aspects that could be fixed to maximize the viewers learning experience, the timeline is a bit confusing. Although it distinctly shows the difference in years, the data is scattered in an unclear order within that year that does not clearly depict what breach happened when. Furthermore, only some of the companies externally show the number regarding the hack and some don't. It is very inconsistent and every companies number should be displayed so the user immediately knows how big the hack was. Also, the timeline is a bit too cluttered. Lastly, the title could be a bit more explanatory. It tells us the timeline is talking about the world's biggest data breaches regarding 30,000 records or more but it is not in a complete sentence and also does not give the time period it is referring to. Furthermore, it does not specify what is being hacked. Although there are some things to fix, the timeline also has many positive aspects. For instance, the timeline lets the user filter the information by different categories such as the organization or method of the leak to narrow their search if necessary, saving the user time and effort. This keeps the user on the page longer because they will not be frustrated. Also, the timeline lets the user click on the bubble for a specific company and the bubble will flip over and provide the reader with more information. Finally, the bubbles are different sizes and colors which is a visual cue that lets the viewer distinguish the size of the hacks without knowing much information. Overall, I like this timeline and it was a positive learning experience.
