D3.js is a JavaScript 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. D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. D3 is not a monolithic framework that seeks to provide every conceivable feature. Instead, D3 solves the crux of the problem: efficient manipulation of documents based on data. This avoids proprietary representation and affords extraordinary flexibility, exposing the full capabilities of web standards such as HTML, SVG, and CSS.
Features
- Readers familiar with other DOM frameworks such as jQuery should immediately recognize similarities with D3
- D3 employs a declarative approach, operating on arbitrary sets of nodes called selections
- You can still manipulate individual nodes as needed
- D3 provides numerous methods for mutating nodes
- D3 provides many built-in reusable functions and function factories
- Using D3’s enter and exit selections, you can create new nodes for incoming data and remove outgoing nodes that are no longer needed
