D3.js is defined as a JavaScript-based library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3's emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.
Mike Bostock wrote D3.js based on his work during his Ph.D. studies at the Stanford Visualization Group. Mike worked at the The New York Times for a while and is now independently working on D3.js.
You can use D3 js because
D3.js uses CSS-style selectors to identify elements on which to operate.
Example:
d3.selectAll("p").style("color", "white");
D3 implements a declarative approach, operating on arbitrary sets of nodes called selections.

In D3.js “Enter” selection is used to create new nodes for incoming data and “Exit” selection is used eliminate outgoing nodes that are no longer required.
There are 7 types of slider are available in D3.js, they are
A transition is a selection-like interface for animating changes to the DOM. Instead of applying changes instantaneously, transitions smoothly interpolate the DOM from its current state to the desired target state over a given duration.
To apply a transition, select elements, call selection.transition and then make the desired changes.
For example:
d3.select("body")
.transition()
.style("background-color", "red");
d3.interpolateObject(a,b) command is used to interpolate two objects in d3.js
