Since this chart is for the Year-End singles in the U.S.A, it is no surprise that it has the highest percentage of American-born artists. This data set is in the context of the top five country of origins and only 60 songs out of the full 68.
While there are some songs that contain a mixed gender artistm the Year-End chart is mostly dominated by male artists. The 1980's is the only decade that shows both male and female to have five songs each year. Other than that, each decade shows males having the most amount of songs.
The relationship between the length (pink line) and beats per minute (green line) of a song has no pattern. The same goes for the beats per minute over the course of the 68 years. It constantly fluctuates. However, the length seems to find a constant range every 5–7 years. Both 1968 and 1981 have a massive spike with lengths almost reaching and exceeding 10:00, respectively. The length seems to find a constant range from 1995 and onwards.
These are the top five genres of the Year-End singles. Please note that these percentages are in the context of all 68 songs, not just the ones selected for this small data set.
Here is the large network graph shown on a smaller scale with the key signatures being the focus. As with the interactive graph, the node (circle) size is determined how many connections it has. This helps to quickly visualize which keys are the most common while simultaneously showing which songs share that key signature. In the case of this graph, F Major is the most popular key signature.
