• The data processing in this assignment really surprised me. Even though DevBootcamp trained me in web development, when it comes to analyzing data, I still very much think in Excel like a management consultant. Not being able to easily save the result of every query into spreadsheets was a big pain and cost me a lot of valuable time.

• D3 was also much harder than I expected. It’s my 2nd time touching D3 (first time was a video tutorial), and I had to put in a lot of work to display the data. For these line graphs, it would have been much easier to work with a more concise tool like Google line charts.

• I really enjoyed this challenge. This was a great review to rails and I learned a lot about working with a greater amount of data.

To examine my work:

data input: /db/seeds.rb

data processing: /lib/tasks/data_processing.rake

d3 graphs: /app/assets/javascripts/scatterplot.js
