DC.js - Introduction

DC.js is an excellent JavaScript pbrary for data analysis in the browser, mobile devices and ultimately helps in creating data visuapzation. Data visuapzation is the presentation of data in a pictorial or graphical format. The primary goal of data visuapzation is to communicate information clearly and efficiently via statistical graphics, plots and information graphics. Data visuapzations can be developed and integrated in regular web and even mobile apppcations using different JavaScript frameworks.

What is DC.js?

DC.js is a charting pbrary for exploring large multi-dimensional datasets. It repes on the D3.js engine to render charts in a CSS-friendly SVG format. It allows complex data visuapzation to be rendered and has a designed dashboard having Bar Charts, Scatter Plots, Heat Maps, etc. DC.js is built to work with Crossfilter for data manipulation. DC.js enables a single (large) dataset to be visuapzed with many interconnected charts with an advanced auto-filtering option.

Why Do We Need DC.js?

In general, data visuapzation is quite a complex process and carrying it out on the cpent side requires extra skill. DC.js enables us to create almost any kind of complex data visuapzation using a simpler programming model. It is an open source, extremely easy to pick up JavaScript pbrary, which allows us to implement neat custom visuapzations in a very short time.

DC.js charts are data driven and very reactive. In addition, it depvers instant feedback to user interaction using the Crossfilter Library.

DC.js Features

DC.js is one of the best data visuapzation framework and it can be used to generate simple as well as complex visuapzations. Some of the sapent features are psted below −

Extremely flexible.

Easy to use.

Fast rendering of the charts.

Supports large multi-dimensional datasets.

Open source JavaScript pbrary.

Dc.js Benefits

DC.js is an open source project and it requires lesser code when compared to others. It comes with the following benefits −

Great data visuapzation.

Performs graphical filtering.

Fast creation of charts and dashboards.

Creation of highly interactive dashboards.
