View a name's popularity over time

[trvslhlt]

In addition to comparing the popularity of names within a date range, we would also like to show users the popularity of single names over time.

• [x] agree upon an API change that allows clients to fetch all annual records for a single name
• [x] use the API to fetch records for a name when the name is clicked in the web app
• [x] display the response in a graph that shows the popularity of the name over time

For the api here, I think we should use the '/names?name=Nathaniel&sex=M' format as an example. The response to this request would be JSON containing records for every year in which Nathaniel was in the top 1000 male names (otherwise there won't be an entry in the database for that year when a name falls below the top 1,000 for the sex in that year).

@tuna42na does that api work for you?

I added the change to the api to allow retrieval of a names popularity over time in the same PR where the year-range functionality was added. The PR is here for reference.

@tuna42na Let me know if this format works for how you want to handle it on the frontend. If you make a request for /names?name=Nathaniel&sex=M you'll get data starting with:

{"id":1147,"name":"Nathaniel","sex":"M","count":60,"popularity":205,"year":1880,"country":"U.S.A.","created_at":"2021-02-19T02:55:59.026Z","updated_at":"2021-02-19T02:55:59.026Z"}

and ending with:

{"id":279000,"name":"Nathaniel","sex":"M","count":3072,"popularity":123,"year":2019,"country":"U.S.A.","created_at":"2021-02-19T02:57:41.863Z","updated_at":"2021-02-19T02:57:41.863Z"}
