D3.js Bar Chart - How do I add this 'data-data' property to my bar graph?

Tell us what’s happening:
I have the graph already working functionally similar to the example given in the challenge… but I am not passing a bunch of the tests. I think it all comes down to ’ User Story #6: Each bar should have the properties data-date and data-gdp containing date and GDP values.’ I can’t figure out what it is asking me to do. I added data-data as an id to my <rect> elements and the data is going to the right place… I don’t know what is up.

Your code so far

data-date and data-gdp should be attributes, not ids.
