Within a week of submitting the first draft of assignment 1, we were given the question for assignment 2. For assignment 2, we had to use world university ranking data available on QS World University Rankings to create a useful infographic and data visualization. Our infographic and visualization had to tie into a common theme. It was recommended that we think of a suitable question related to university rankings and try to answer that question using the infographic and visualization.
As in the case of assignment 1, the first challenge I faced was deciding what data to use from QS world university rankings. I also had to decide what theme I wanted focus on and what question I was trying to answer with my work. Deciding the theme and question was extremely hard as there were so many avenues I could explore. I could explore rankings country-wise or region-wise. Alternatively, I could consider a more ‘causal’ approach by focusing on what has caused the rankings of universities to be where they are. A third approach would be to dig deeper into a particular parameter such as academic reputation, employer reputation, cost of living, student life etc. Ultimately, I decided to focus on the top universities in a particular region or country. This would narrow down my data tremendously. Moreover, I could explore various parameters of the top universities in depth. Now that I had decided to focus on a region or country, I was confused about which region or country to pick. My primary contenders were Asia and the US. Asian schools have been climbing in the rankings and might show some interesting trends over the years. However, top US universities are ranked very high worldwide and might be more popular amongst prospective students. After weighing the pros and cons of both my options, I decided to concentrate on the top 10 US universities. Top US universities are very popular choices for students from all around the world because of their high international intake. Moreover, they offer very interesting courses and opportunities. I thought that my infographic could educate the reader about the top 10 US universities and give the reader some interesting facts and figures which might be useful to him / her while picking his / her university.
Now that I had decided what data and theme I would be focusing on, I started thinking of some potential ideas for my infographic. My simplest idea was to draw a map with the locations of the top 10 US universities indicated on the map. I thought it would be an interesting statistic to include the percentage of top schools on the east coast and west coast. I also wanted to compare parameters such as tuition fees, academic repute and employer repute of the top schools. However, due to lack of time, I was unable to include all the elements I wanted in my first draft. Hence, my first draft was incomplete and looked like this:
As the draft was incomplete, I was unable to get a lot of concrete feedback for it. In general, people felt that the data I had represented so far was a bit disconnected and none of it was really very useful to prospective students. I had to find a better way to convey the information I was interested in sharing.
To me, thinking of a good design that is both aesthetically appealing and in accordance with design principles is the most challenging task. I was extremely confused about how to represent all the data I had in a clean and understandable way on the infographic. I looked for inspiration online and came across this infographic:
The inforgraphic and related article can be found at China Knowledge Revolution
I was impressed by the following elements of this infographic:
- A clear heading to indicate its purpose.
- Use of a map to depict locations of universities.
- Use of different kind of charts such as 3D line chart and progress bars to indicate various statistics.
Overall, all the elements of the infographic tied into a common theme and told a coherent story. In a similar manner, I wanted my infographic to very clearly depict the central theme I had chosen. I thought of all the information I wanted to convey and what would be the best way to convey it. I thought of all the elements I needed in my infographic and came up with the following list:
- Location of top 10 universities in US – best way to depict this is a map with the universities marked out.
- Ranking of the university in US.
- World ranking of the university.
- Top subjects of study in each university.
- Acceptance rate in each university – good way to depict this is a status bar with the percentage acceptance rate.
- Comparison of tuition fees of top 10 US universities – this could be done using a horizontal / vertical bar graph.
- Comparison of academic reputation of top 10 US universities – this could be done using a horizontal / vertical bar graph.
- Comparison of employer reputation of top 10 US universities – this could be done using a horizontal / vertical bar graph.
As with assignment 1, I decided to use the online tool Piktochart to put the various elements of the infographic together. My completed infographic for assignment 2 looked like this:
I was pleased with my effort and felt that my infographic was very clear in its central theme. It provided a good insight into the top 10 US universities and helped answer questions students may have regarding tuition fees, acceptance, top subjects or academic repute.
The next step was to create a data visualization again surrounding my central theme of top 10 US universities. As per its wiki definition, data visualization is “information that has been abstracted in some schematic form, including attributes or variables for the units of information“. I decided to focus my visualization on how the world rankings of the top 10 US universities had changed over the past 10 years. This dataset included numerous data points and could be well represented using a line graph. I collected the rankings of the top 10 US universities over 10 years (from 2004 to 2014) on the QS world rankings website. I put all my data into an excel sheet and decided to use Tableau public to plot my graph. Tableau lets you import data from excel sheets while plotting. I used this feature to import the ranking data I had saved on excel into Tableau and was easily able to plot line graphs for each university. My completed visualization looked like this:
My primary takeaways from assignment 2 are:
- Use of tools like Illustrator, Piktochart and Tableau.
- Understanding differences between a visualization and inforgraphic.
- A better understanding on how to design a good quality infographic.
I enjoyed the process of creating the infographic and visualization for assignment 2. I think I have been able to improve my designing skills and I hope they will continue to improve over the course of this module.
