A good question, that is.
You are looking at a data visualisation of the sentiment of Star Wars Episode IV: A New Hope.
Every dot is a line by one of the main characters in the movie.
The position on the y-axis resembles the sentiment score: from negative to positive.
The higher a dot is plotted, the more positive is the line behind it.
The size of a dot is the magnitude of the emotion.
You could say that a big dot is more powerfully expressesed than a small one.
The x-axis is the timeline of the plot.
This allows you to see where the lines appear in the movie.

Another good question, that is. The input for this visualisation was this data set on Kaggle. The data was analysed line by line using Natural Language API by Google. After that, I visualised it as a scatterplot in Python using Matplotlib and stored it as an SVG. The interactive web version was made using plain HTML, CSS, and JavaScript. During the process, I accompanied myself with this playlist.
