Barrett has been practicing all of this stuff in his day job for many years&ndash;Postgres, D3, GIS, all of it. The knowledge in this book is real-world and hard-earned!&rdquo;</p> <p style="margin:0px;"> </p> </i> <p style="margin:0px;">&ndash;From the Foreword by Obie Fernandez <br> </p> </blockquote> <p style="margin:0px;"> <i> <b>Data Visualization Toolkit</b> </i> is your hands-on, practical, and holistic guide to the art of visualizing data. You&rsquo;ll learn how to use Rails, jQuery, D3, Leaflet, PostgreSQL, and PostGIS together, creating beautiful visualizations and maps that give your data a voice and to make it &ldquo;dance.&rdquo;</p> <p style="margin:0px;">&nbsp;</p> <p style="margin:0px;">Barrett Clark teaches through real-world problems and examples developed specifically to illuminate every technique you need to generate stunningly effective visualizations. You&rsquo;ll move from the absolute basics toward deep dives, mastering diverse visualizations and discovering when to use each. Along the way, you&rsquo;ll build three start-to-finish visualization applications, using actual real estate, weather, and travel datasets.</p> <p style="margin:0px;">&nbsp;</p> <p style="margin:0px;">Clark addresses every component of data visualization: your data, database, application server, visualization libraries, and more. He explains data transformations; presents expert techniques in JavaScript, Ruby, and SQL; and illuminates key concepts associated with both descriptive statistics and geospatial data. Throughout, everything is aimed at one goal: to help you cut through the clutter and let your data tell all it can.</p> <p style="margin:0px;">&nbsp;</p> <p style="margin:0px;">This guide will help you</p> <ul> <li>Explore and understand the data visualization technology stack</li> <li>Master the thought process and steps involved in importing data</li> <li>Extract, transform, and load data in usable, reliable form</li> <li>Handle spotty data, or data that doesn&rsquo;t line up with what your chart expects</li> <li>Use D3 to build pie and bar charts, scatter and box plots, and more</li> <li>Work effectively with time-series data</li> <li>Tweak Ruby and SQL to optimize performance with large datasets</li> <li>Use raw SQL in Rails: window functions, subqueries, and common table expressions</li> <li>Build chord diagrams and time-series aggregates</li> <li>Use separate databases or schema for reporting databases</li> <li>Integrate geographical data via geospatial SQL queries</li> <li>Construct maps with Leaflet and Rails</li> <li>Query geospatial data the &ldquo;Rails way&rdquo; and the &ldquo;raw SQL way&rdquo;</li> </ul> <!--[if gte mso 9]> <xml> Normal 0 false false false EN-US X-NONE X-NONE </xml> <![endif]--> <!--[if gte mso 9]> <xml> </xml> <![endif]--> <!--[if gte mso 10]> <![endif]--> Author: Clark, Barrett Publisher: Addison-Wesley Professional Illustration: n Language: ENG Title: Data Visualization Toolkit: Using JavaScript, Rails, and Postgres to Present Data and Geospatial Information Pages: 00256 (Encrypted EPUB) / 00256 (Encrypted PDF) On Sale: 2016-08-04 SKU-13/ISBN: 9780134464435 Category: <!-- COM021030 -->Computers : Database Management - Database Mining Category: <!-- COM051010 -->Computers : Programming Languages - General
