How to Visualize Data with D3.js Developer

The buzz about D3 JS began around 2011 when the unique JavaScript library emerged in the development world. D3.js, also referred to as D3, is a library that JavaScript developers use to produce dynamic, interactive data visualizations in web browsers. While many other libraries limit control over the final visualizations, D3 JS visualization allows developers the opposite. This is the leading attribute that contributed to the rise in popularity of this unique library.

D3.js Developers and Their Demand

The increased control on final visualizations that is offered to a D3 JS developer when using the library has certainly added to the rise of its popularity since it became available. Used in hundreds of thousands of websites, D3 can help create interactive graphics for a variety of needs. From online news websites to maps and data viewing dashboards, D3 JS charts are the top choice for the imperative approach to data visualization.

The D3 programmer uses the control of D3.js to construct SVG objects and extract them as they see fit. When a charting library cannot appropriately deliver the visual aspect of data that is needed, D3.js is the solution. The D3 JS chart library allows developers to take their visualizations and create graphics that are interactive and animated. Mike Bostock, the creator of D3.js, used the JavaScript library to create some very well-known infographics for popular news websites like the New York Times. His interactive and animated graphic for the 2012 “512 Paths to the White House” shows just how might the library can be.

Another reason the D3.js library is so popular amongst D3.js consultants is because of the years of work spent trying to bring data visualization to web browsers. Prefuse, Flare, and Protovis toolkits are all considered the predecessors of D3.js. Mike Bostock was involved with all three of these tools. Using his experience from these JavaScript libraries, Bostock set out to develop the D3.js framework to create a more expressive option that provided improved performance for developers.

All About D3.js

D3.js is a JavaScript library that manipulates documents based on data. Developers can bring their data to life by entering code that executes their data step-by-step. Using HTML, SVG, and CSS, D3 can fix random data to a Document Object Model, or DOM. Data can then be arranged into interactive charts that offer a dynamic experience to those viewing the data. The open source library offers an assorted collection of official and community-developed modules.

While there are many pros listed for using D3.js, there has yet to be seen any disadvantages of using the library. In addition to being extremely fast and capable of supporting huge datasets and dynamic behaviors for interactions and animations, the pros of D3.js include:

advantages of d3 js visualization

Many developers choose to build complex visualizations. When doing so, they combine different technologies for a multipart outcome. It is important to note, not all technologies work together. And some may work together, but not be the most effective solution for executing the data visualization. As D3.js became popular, developers started to work to see what technologies would work best with the JavaScript library. Two of the most popular technologies combined with D3.js are React and TypeScript. While D3 React JS can be an extremely powerful tool, there are many challenges that lie in combining the two. Still, they work together very well.

When developers decide who own which parts of the DOM, they can successfully combine React with D3. The decision depends on what you are trying to build and developer preference. And, many developers have chosen to use a hybrid approach where they use the strengths of each framework to manage the DOM.

In some cases, D3 is also used with Node for server-side data visualizations. Because D3 can be used to generate static data visualizations as well, some developers choose to combine the technologies of D3 and Node to execute CSS styling and stylesheets. D3 Node JS can allow developers to output an SVG from a JS source file, your data, and the command line. A D3 Node JS example uses D3 on both front end and server to generate images with Node.js.
