Build dynamic and interactive visualizations from real-world info with D3 on AngularJS

About This Book

  • Explore the strong vector pictures functions of contemporary browsers to construct custom-made cross-platform visualizations utilizing D3.js's data-driven techniques
  • Learn the way to modularize a visualization into reusable and testable parts utilizing the robust options of contemporary internet software layout with AngularJS
  • This is a step by step studying advisor heavily interested in constructing responsive info visualization apps and AngularJS top practices with D3.js

Who This publication Is For

If you're a internet developer with event in AngularJS and need to enforce interactive visualizations utilizing D3.js, this ebook is for you. wisdom of SVG or D3.js provides you with an aspect to get the main out of this book.

What you'll Learn

  • Design, enforce, and combine an interactive dashboard to imagine server logs in actual time utilizing D3 graphics
  • Learn cross-platform vector pictures to enforce a dashboard visualization
  • Perform data-driven variations on chosen HTML and SVG nodes
  • Map, team, and filter out datasets and create scales and axes
  • Modularize information visualization info into reusable elements to seamlessly combine them into an AngularJS application
  • Load, parse, and preprocess exterior info and autoupdate the visualization
  • Design a number of chart varieties equivalent to scatter, line, bar, or zone and expand integrated shapes
  • Create customized animations and transitions for the visualization
  • Implement interactions and controls for the visualization conserving two-way binding among D3 and AngularJS components

In Detail

Using D3.js, the strong JavaScript toolkit for developing cross-platform vector photos, now you can mix functionality with greatest compatibility to construct an online visualization and current facts in an interactive and handy manner. we are going to achieve top-notch reusability and testability via combining D3 pics with our favourite net program framework, AngularJS.

This publication teaches the fundamentals of vector snap shots, D3, and AngularJS integration, after which dives into controlling, manipulating, and filtering info. you'll find out about the testability of elements and the way to enforce customized interactions, filters, and controllers; observe the way to parse and map info in D3.js; and get a clutch on drawing D3.js integrated shapes and curves. After examining the previous couple of chapters, one could deliver existence for your visualizations with extra positive aspects of D3.js equivalent to interactions, animations, and transitions. you are going to end your trip by way of imposing a parser for various server program logs and exhibit them on a Google Analytics sort interactive dashboard.

Beautiful Data

During this insightful ebook, youll study from the easiest facts practitioners within the box simply how wide-ranging -- and gorgeous -- operating with facts could be. sign up for 39 participants as they clarify how they built uncomplicated and chic suggestions on initiatives starting from the Mars lander to a Radiohead video. With attractive facts, you are going to: discover the possibilities and demanding situations fascinated by operating with the great variety of datasets made on hand by way of the net the way to visualize tendencies in city crime, utilizing maps and information mashups become aware of the demanding situations of designing a knowledge processing process that works in the constraints of house shuttle learn the way crowdsourcing and transparency have mixed to improve the nation of drug study know how new info can immediately set off indicators whilst it fits or overlaps pre-existing info find out about the large infrastructure required to create, trap, and approach DNA info Thats merely small pattern of what youll locate in attractive info.


Metaheuristics show fascinating houses like simplicity, effortless parallelizability, and prepared applicability to kinds of optimization difficulties. After a accomplished advent to the sector, the contributed chapters during this publication contain causes of the most metaheuristics concepts, together with simulated annealing, tabu seek, evolutionary algorithms, man made ants, and particle swarms, by way of chapters that show their functions to difficulties comparable to multiobjective optimization, logistics, car routing, and air site visitors administration.

Example text

The resulting image generated by the previous code will look like the following figure: Image of three circles Raphaël (JavaScript – SVG/VML) By 2008, most of the major browsers provided native support for SVG and signified the certain end of Flash in the upcoming years. However, Internet Explorer implemented a different markup language for vector graphics than SVG; it used the similar, but different Vector Markup Language (VML). In 2009, Dmitry Baranovskiy announced the first release of Raphaël, a JavaScript library that aims to simplify the manipulation of vector graphics by providing a JavaScript API for SVG with a compatibility layer for VML for Internet Explorer.

The representation of graphics inside the DOM not only enabled the use of JavaScript event handlers for user interactions on elements of the image, but it also enabled the use of CSS to style these elements. This was a huge step towards open web standards, accessibility, and acceptance of SVG. attr('fill', 'red'); } Again, we generate a circle with the x coordinate of the data array each time we loop over the array. In a modern browser, the preceding code produces an SVG image that looks exactly like the previous example, but additionally outputs directly to the DOM of the HTML page.

Document Object Model The Document Object Model (DOM) is the tree representation of the hierarchical elements of an HTML document and it was specified by the World Wide Web Consortium (W3C). These elements in the DOM are called nodes (for example, html, head, body, and so on), which can have attributes (for example, class="header") and content (for example, "My Application" is the content of the h1 node). The DOM provides a public JavaScript interface with which we can access nodes and manipulate them.
