Explorer: Data exploration tool

We wanted to expose data for our customers at Close.io about their sales activities, communication, etc. based on their usage.

Rather than add a bunch of individual "reports" we opted to build a single tool that would allow creating a huge number of different useful charts. By changing the various dropdowns you can control the "x" and "y" axis, and the chart type itself will detect the type (e.g. line vs. column chart) and other parameters automatically.

Launched: http://blog.close.io/introducing-explorer-customizable-reporting-graphs

UI is built using custom JavaScript, Highcharts (with customized CSS and JS), LESS, and a bit of Bootstrap
Backend is powered by Elasticsearch
