Here’s a visualization of the relative frequencies across all sections and chapters of the book.
Each coloured bar represents a section and is colour-coded for Earth sections (green) and Space sections (purple).
The grey bars represent the chapters, which are marked with ticks and numbers.
The y-axis is the relative frequency, i.e. the proportion of tokens in that section (or chapter) that match “gravity” (so a bar might be higher, even with fewer occurrences, if the section or chapter is shorter).
That’s a lot of gravity
