Some elements may come from more than one source which are listed below:
- Big Bang fusion
- Exploding white dwarfs
- Exploding massive stars
- Cosmic ray fission
- Merging neutron stars
- Dying low-mass stars
- Human synthesis
I wanted to see counts of elements by origin. At first I thought I might have to do some manual data entry from the graphic.
However, after a bit of digging it turned out that the author of the SVG file had embedded the data and Python code necessary to create the SVG file inside the file which is very cool.
With some minor modification to the Python code I was able to extract the data into a csv data file and then use that as data source for the visualizations of counts of elements by origin below.
Read more about the SVG and the Python code modifications here https://github.com/sitrucp/periodic_elements.
The first chart below shows the counts of elements by their origin which answers my question.
