3.3 Raw Sum of Articles
Here is what it looks like if we just count how many articles are in each topic each year.
There are so many overlapping dots that it isn’t that helpful a graph. It’s a bit clearer when the topics are broken out.
Note a couple of things about this as compared to the graphs back in section 3.1. One is that the y-axis is much higher. The raw count measure tends to amplify trends. Another is that the graphs are much noisier. There are still enough trends that I don’t think it would really help to add trend-lines, but there are a lot more graphs that look just like scattered points, especially over ten-twenty year patches. I think this is basically a flaw in the underlying measure being amplified.
The animation makes things a bit clearer here because the original features so many overlapping dots.
