I collected a data-sets which tested for many users (>100.000) which out of ten features in a software-product they use. They can use multiple features but for each feature there is only "use" or "don't use". So in terms of software-development, I have many sets of features in a length of zero to ten.
I want to visualize the data in such a way, that it answers two questions:
- Which features of the software are the most popular ones; How many percent of the users use FeatureX?
- Which features are most often used together? So which sets of features are the most popular. For example, if most people tend to use Feature1 together with Feature2 (no matter what other features they use or don't use), I want to see this somehow in my visualization.
To clarify: The data is already collected, I'm searching for a good way to show this data.
I'm not sure whether you can (and should) visualize this in one graph or whether you should choose to display multiple graphs.
I came up with a simple solution for 1.: Creating a bar-graph which shows for each feature how many people selected it solves this problem. But it doesn't help for 2.
