I've conducted a survey of 20 questions using a 5-item Likert scale in which 10 people participated. In each question, the participants were presented with two versions of a picture and asked to pick the better one. The obvious way to visualize the data would be something like this:
However, I'm losing some information with this representation. I want to show that if a participant $p_1$ chose an answer $x$ for a specific question $q$, then what did they choose for the other questions?
In other words, I want to know just by looking at the graph if another participant $p_2$ who gave the same answer $x$ to the same question $q$ also agrees with $p_1$ with the rest of the questions. How can I visualize this information?
EDIT: Here's the data as a .csv file:
picture_1,picture_2,picture_3,picture_4,picture_5,picture_6,picture_7,picture_8,picture_9,picture_10,picture_11,picture_12,picture_13,picture_14,picture_15,picture_16,picture_17,picture_18,picture_19,picture_20 4,4,2,2,4,2,3,5,3,4,2,5,2,1,4,4,2,1,5,2 2,2,4,4,4,2,2,2,4,4,2,4,2,2,3,2,2,4,5,2 4,5,4,1,4,2,2,4,4,3,2,2,2,1,2,4,4,2,5,4 3,4,2,4,4,2,2,2,4,3,2,4,4,3,3,4,2,4,5,1 4,4,3,2,4,3,4,5,4,3,1,5,3,2,4,2,2,3,4,2 4,5,2,3,5,1,3,4,3,3,1,2,4,4,5,4,1,4,5,4 5,5,5,2,4,3,2,4,4,2,2,4,4,2,4,2,2,4,4,5 4,4,3,1,5,3,2,4,2,2,1,4,4,2,4,1,2,5,5,3 1,3,5,2,4,4,3,1,4,4,2,3,1,4,3,4,3,3,4,1 3,3,5,2,4,2,4,4,3,4,1,5,4,2,1,2,2,4,5,2
The rows are participants and the columns are the questions. $1$ corresponds to "left picture is much better", $2$ to "left picture is somewhat better" $...$ and $5$ to "right picture is much better".
