Comparing Products to Find the Best Fit
Comparison charts are a great way for consumers to compare multiple products from a company in order to determine which one is right for them. Let’s take the company Apple for instance. They provide many options on buying an IPad, but how do you know which one to get? There are many different charts that you can look at in to determine which one is best for you. First let’s start with the basics. Think about what you are using the IPad for. If you are simply taking notes then a regular IPad will do just fine. However if you plan to use it for editing or designing you might want to look closer at display sizes and resolution options.
Another way to compare them is how well they perform. Someone who needs this device for high demanding and important work may wanna go with the IPad that has a higher megabit speed.
Lastly, and I think the most important to a lot of people, is how much each device costs. Comparison charts like this allow you to gauge how much this investment could cost you. Charts like the one below or the two above can usually be found on the company’s website or online forums for tech users.

Comparing Numbers
I came across an interesting dataset and a corresponding visualization that compared the characteristics of Barack Obama and Mitt Romney during the 2012 US presidential debates. The graph in question is a radar plot displaying 12 characteristics of the candidates’ words during the debates. These characteristics include “directness,” “talkativeness,” “sophistication,” and more.
However, I found the radar chart a bit challenging to interpret effectively when comparing the two candidates. I’d like to discuss two valuable tips that can make such comparisons clearer when using graph visualizations:
- Graphing the Differences: When comparing two groups, it’s often more intuitive to graph the differences between them rather than plotting each group separately. This can help viewers focus on what sets the groups apart. In the context of the 2012 debates, this could mean creating a graph that visually emphasizes the differences in characteristics between Obama and Romney, making it easier to identify distinctions in their speaking styles.
- Sorting Categories by Meaningful Quantity: In any plot that has a categorical axis, it’s essential to sort the categories by a meaningful quantity. This ensures that the visualization effectively conveys the message you intend. For instance, if the radar chart includes characteristics like “directness” and “sophistication,” consider sorting these characteristics in a way that highlights the most relevant differences between the candidates.
As for the dataset provided, it appears that the numbers represent the relative percentages of each characteristic attributed to Obama and Romney during the debates. For example, in the category “Individualism,” 47% of the phrases were attributed to Obama, while 53% were attributed to Romney.
