To build the SDK to be small and use the integrations server-side only, add the following to your Podfile:

  pod 'Analytics/Segmentio', '~> 2.0.9'
  ... and to add any individual bundled integrations:
  pod 'Analytics/GoogleAnalytics'
  pod 'Analytics/Mixpanel'
  ... // the subspecs for additional bundled integrations are all listed here:
  ... // https://github.com/CocoaPods/Specs/blob/master/Specs/Analytics/2.0.9/Analytics.podspec.json

This simple line chart is constructed from a TSV file storing the closing value of AAPL stock over the last few years. The chart employs conventional margins and a number of D3 features:

This also uses simple-statistics to derive a linear regression of the price changes.

• d3.tsv - load and parse data
• d3.time.format - parse dates
• d3.time.scale - x-position encoding
• d3.scale.linear - y-position encoding
• d3.extent - compute domains
• d3.svg.axis - display axes

If you have node installed, you can clone the repo for whichever integration you'd like to use (say GA) then install segmentio-facade:

git clone https://github.com/segmentio/integration-google-analytics.git
cd integration-google-analytics
npm install segmentio-facade

Then create a new file in the top level of the directory with the script from this gist.
