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.

Popular Projects Made with D3.js

There are many companies currently using D3.js. To name a few, these include:

Inspired by the popular Ted Talk, “The Wealth of Tech Companies” uses D3.js to create a motion chart displaying annual income and revenue of popular technology companies such as Google, Microsoft, Amazon, and Facebook. Developers can even create dragging maps that allow you to navigate across multiple areas like the popular Pixymaps. With D3, the opportunity for interactive, dynamic charts are endless and many popular companies and developers use the JavaScript library in their D3 projects.

The Future of D3 Development

The future of D3 for developers skilled in it looks bright. As Artificial Intelligence continues to gain popularity, D3 is an influential part of engaging dialogues with viewers around AI. There are many reasons developers should learn D3 as we head into 2018. In addition to the demand for interactive graphics on the web today, those skilled in D3 are often more hirable. They have a multitude of skills across the board from their experience with D3.

While the demand for D3 developers in the place like England, Scotland, and Yorkshire has seen a decline, many other countries have seen a rise in demand. The South East and the UK excluding London, for example, have seen a significant rise in demand. When combined with multiple skills with libraries and framework, D3 developers in the US see a range in salary depending on the job title they hold.

What Is the Salary of a D3 Developer?

According to PayScale, D3 developer salary in the US can bring in an average of $87,600 a year as a Software Engineer. Additionally, Data Scientists skilled in D3 average $98,900.

Interview with D3 Developer

Due to the popularity of D3.js we have asked our dedicated developer Oleg about this technology, his vision of its development, pros and cons.

What do you think about D3.js demand and popularity?

d3.js developerIf we talk about the demand for d3 then it stays at the same level. A large number of projects still use this library to display statistics and graphs and are unlikely to update it in the near future. D3 is greatly optimized for SVG, which makes it an excellent library for display, but now most libraries have migrated to canvas + WebGL, which increases the performance of displaying data in fold times. But D3 has a large number of different mappings as well as additional auxiliary functions that are not available in other libraries.

You can always link d3 with any framework, such as React or Angular.

Which pros and cons of D3.js can you pick out based on your experience?
d3.js developer

The main benefit of D3.js is that the code is logically constructed and customizable for any of your needs, as well as a large community and documentation,  will help you in the development of submissions. D3.js is hosted on GitHub and its code is open to anyone who wants. It also has a large number of instances of different charts that you can use in your project and modify it as you like. If we talk about the advantages of D3.js, this framework is powerful and have the next benefits:

  • It free – you can get the last version from GitHub and using documentation create the awesome chart.
  • Flexible – D3.js very flexible, you can control any DOM item and gave him different skills.
  • Highly Dynamic – you can create a dynamic animation on your pages where all were smooth and cool.
  • Data – had a lot of functions for working with data

The main disadvantage is that the library only works with SVG, but now it’s not as relevant as a canvas. Can you ask why? The problem is that SVG is created with the help of DOM nodes, and their number on the page complicates the work of the browser with the transfer, which turns out that the more graphs on the page the more difficult your device to repaint it.

Can you tell us more about projects with D3.js you have worked with?

d3.js developer

My first project where I used D3.js was on the landing page where we should combine much information from users and servers. We are building different charts and the main page where you can check various information. On the next project we are building service for renting flat it looked like on Airbnb, and we generate price charts dependents on the district. And many other charts for better user expires in the selection new flat. My last project was a trading system were you can checking currency pair in real time. For example, you are selected EUR dependent of USD, so all different between this currency checking and showing on the chart. We had 2 different charts:

  • Line chart – it’s basic chart what shows data for two parameters on my option it was time and price.
  • Candles chart – it’s a special chart where you can check 5 values on one candle: time, open price, closing price, high price, low price and status.

How do you see the development of D3.js framework? Which features would you like to see in future?

d3.js developer

D3.js did not update for several years and I have not heard any information about the following updates or further development. Maybe, in the future, they will make some updates or add new functionality, but it is unlikely. The only thing I can expect from them is the canvas & WebGL support because this future and the bulk of modern libraries use this approach because it requires less memory and resources. Currently, we have to use some additional third-party libraries that help you implement it or hand it over to your own.
