Where to Find and Access Big Data
This is a great visualization of all the different sources for big data, including the velocity, variety and volume of the specific source, and how structured it is not only smart in design but also practical in nature.
Best place to do business?
I found this very interesting “daily chart" from The Economist magazine’s website. As enlightening as it is, I really wish that they could have made an interactive version of this, like being able to show or hide certain areas, so that we can read the data better. Right now, because everything is static, some dots clasped together — as it is the case on the third horizontal line "Getting Electricity."
But this data visualization does tell a compelling story. Representing “OECD high income” countries, the red dots get the best scores on almost every criteria, meaning that the most well-off countries are also the friendliest ones for entrepreneurs and business.
Bundestagswahl 2013 data visualization
The following info-graphics come from 2013 German parliament election, which just took place on September 23. I was following the election results for my German class and that’s why I came across with these graphs.
Although all it takes here is a “simple” visualization using bar and donut charts, I am quite impressed by how clean and intuitive these graphs are. The first bar chart shows the percentage of votes each party gets, while the bar chart below illustrates how much does the popularity of the party increase or decrease in this year’s election compare to last year. The half-donut chart shows the numbers of seats each of the four parties gets in the parliament. The horizontal bar chart shows the absolute majority gained by the Union (CDU & CSU). And lastly, the last one illustrates the possible coalitions between parties based on this year’s election results.
Using the party colors is also quite effective; since the majority of the voters are familiar with the colors representing these parties, it makes it very easy for them to tell the results.
CNN Money unemployment rate infographic
This week’s data visualization example, “Unemployment rate, state by state,” is from CNN Money. In comparison to other examples I’ve discussed here, this infographic is by no means sophisticated, but rather simple yet powerful.
Two features that I found extremely useful:
1. Color Strategy
It is smart, in this particular case, to indicate the degree of unemployment through a change of the color value. This color strategy makes it very easy for us to spot the pattern that, in general, states located from mid to south west areas are doing a better job than those from the southeast and the coasts.
2. The “Pop Effect”
Maybe it is not the most appealing example of the data you are looking for just show up intuitively for you, but when you hover your mouse over each individual state, that state will enlarge and pop out, with a dialog window showing the name of the state and the UE rate. The font size is also large enough to be easily identified and read, which can be very helpful for people with a weak eyesight.
