Data Visualization Toolkit  offers a hands-on, practical, and holistic approach to the art of visualizing data. You'll learn how to use Postgres, Rails, D3, and Leaflet to create beautiful visualizations and maps that give your data a voice--and make it dance!

Barrett Clark teaches through real-world problems and examples developed specifically to illuminate the concepts and techniques you need to generate highly effective data visualizations. You'll move from the absolute basics towards deep dives, mastering diverse visualizations and gaining an expert understanding of when to use each.


Coverage includes

  • ActiveRecord and D3: making charts, transforming data, incorporating interactivity, and large data sets
  • Generating data-driven answers to specific questions
  • SQL In Rails: Using Window Functions, Subqueries, and Common Table Expression in Rails
  • Geospatial Rails: Using and querying geospatial data with PostGIS, and building maps with Leaflet


Everything here is aimed at one goal: to help you cut through the clutter and let your data tell you all it can.
