D3.js Tutorial

The acronym D3.js is mean for the Data-Driven Documents. It is a library of JavaScript that is used to employ the documents on the basis of data. The Data-Driven document is an interactive, dynamic, online info visualization framework applied inside the large number of websites.

D3.js is specified by Mike Bostock. The previous visualization toolkit is known as Protovis. The D3.js tutorial will provide us all information on the D3.jsframework. It is the introductory tutorial that will cover the basics of the Data-Driven Document. It also specifies how to manipulate its several elements and sub-elements.

Introduction

The data visualization concept is the data presented inside a graphical or pictorial format. The primary objective of data visualization is to convey the information efficiently and clearly by information graphics, statistical graphics, and plots.

Data visualization supports us to convey our insights effectively and quickly. Any data type, illustrated by the visualization permits us to analyze the data, understand patterns, generate analytic reports, and hence support them to attain a decision. Thus, users can examine the specific data inside the chart. The data visualizations may be integrated and designed inside mobile applications and even regular websites with the use of the distinct frameworks of JavaScript.

What is Data-Driven Document?

D3.js is the library of JavaScript applied to make interactive visualization inside the browser. D3.js library permits us to employ the webpage's components in the data set's context. These components may be Canvas elements, SVG, or HTML and may be edited, removed, and introduced according to any data set's contents. It is the library to employ a DOM object. The D3.js may be any valuable aid inside the data exploration, and it will provide us control on our representation of data and allows us to add interactivity.

Need of D3.js

It is a foremost framework if compare to any other libraries. It has great implementation over the web due to its flexibility. After all, it executes seamlessly along with the current web automation and can employ any specific piece of a document object model. The D3.js is as extensible like the client-side Technology Stack (SVG, CSS, and HTML). It has the great support of the community and is efficient in learning.

Features of D3.js

D3.js is the best framework for data visualization. It can be applied to produce simple and complex visualizations with the interaction of users and the transition effects.

A few salient characteristics are as follows:

  • Code Reusability
  • Declarative Programming
  • Large Datasets Support
  • Fast and efficient to use
  • Extremely Flexible
  • Includes curve producing function's wide variety
  • In an HTML page, relates data to the components and group of components.

Benefits of D3.js

D3.js is the project of open source type and executes without a plugin. It needs very fewer codes.

Some of the essential benefits of D3.js are discussed below:

  • DOM manipulation
  • Strong data visualization
  • Efficient to build any charting component
  • D3.js is modular. We can download any small part of D3.js that we wish to use. There is no requirement to load an entire library all the time.

Prerequisites

It is simulated that the learners should have enough knowledge about a framework, before going to start with several kinds of concepts provided inside this tutorial. It will be easy for learners having sound experience in JavaScript, CSS, and HTML.

Audience

This Data-Driven Document tutorial is designed for the professional interested in making his/her career in the online info visualization. It is proposed for making us comfortable to get started with D3.js and its several functions.
