I am a student who has primarily used languages such as Python and MATLAB, so I am having a bit of trouble with Javascript. The assignment is to create a scatterplot based on this data. I understand how to create the plot, but I can't necessarily figure out how to only extract the integer elements of the set. I typically work with large dictionaries in Python and understand the traversal of those. But since strings and integers are essentially combined here, I am not sure how to traverse this data set. Any help would be greatly appreciated. Thank you!
