D3 D3 stands for Data Driven Documents D3 also sometimes referred to as D3 js is an open source JavaScript library for manipulating documents based on data D3 is a dynamic interactive online data visualization framework D3 is an important tool for people who re interested in visualizing data What is a Framework Frameworks provide you with the foundation necessary to build JavaScript applications This saves you the effort of starting from scratch by utilizing a functional base to get things rolling In JavaScript s case this base includes a collection of code libraries The libraries compile code that elicits specific functionality for your specific program needed In essence a framework defines a structure for you to use Introduction Data visualization is the means of communicating information clearly and efficiently via pictorial or graphical means These graphical means may include statistical graphics plots 3 dimensional renders and more Through D3 you ll be able to communicate your insights quickly and effectively You ll be able to visualize and compare data in novel ways that show patterns and trends Since D3 is a JavaScript framework developed to run in a web browser you ll be able to develop and distribute your data visualizations in websites and mobile applications img src https notebook xbdev net var images d3 jpg style margin 0 width 100 Don t underestimage the power of visualizing your data Why is data visualization important The human brain processes information visually so using charts or graphs to visualize large amounts of complex data is easier than poring over spreadsheets or reports Also data visualization can help identify areas that need attention or improvement What is D3 D3 js The Data Driven Documents library known as D3 or D3 js is a powerful interactive visualization framework written in JavaScript for the web D3 uses the web browser elements HTML CSS SVG and Canvas and the Document Object Model DOM to generate and create content to meet you and your datas desired needs D3 is an especially valuable tool for data exploration since it gives you complete control over your data s represenation not to mention how you interacte with that data What is the Document Object Model DOM The Document Object Model DOM is a programming API for HTML documents It defines the logical structure of documents and the way a document is accessed and manipulated The DOM is used as a way of representing many different kinds of information and much of this would traditionally be seen as data rather than as documents The Document Object Model DOM connects web pages to scripts or programming languages by representing the structure of a documentsuch as the HTML representing a web pagein memory Why do we need D3 D3 is a popular well established open source framework that runs in most web browsers D3 has a vast assortment of excellent visualization resources support documentation and examples However one of the reasons why D3 is and remains so popular is owing to its flexibility D3 integrates and works seamlessly with web based technologies e g HTML CSSS and SVG including having a large and helpful community of users and developers which is compouned by its accessibility and straighforwardness to learn D3 Features D3 is able to work with a vast assortment of data types to create both simple and complex visualizations These visualizations can also be animated and interactive Customized user experiences and transition effects To list some of the key features Easy to user and get started Free and open source Extremely flexible Supports large datasets Declarative programming Code Reusability Wide variety of curve generating functions Associate data to elements and groups with the html on the web page img src https notebook xbdev net var images blocks jpg style margin 0 width 100 D3 Benefits Since D3 is an open source project written in Javascript it does not requre any plugins In fact the library itself is very compact and small Homepage development https d3js org https d3js org Latest version 2 10 3 License free under BSD Minified size 116 kb Few of the core benefits and the rational behind its development are Modular library download the full library just small pieces depending on your needs Powerful eye catching visualizations stand out from the crowd Enables DOM manipulation controlling web page Easy to extend create basic standard charts visual components Easy to install
DOM The Document Object Model DOM is a programming API for HTML documents It defines the logical structure of documents and the way a document is accessed and manipulated The DOM is used as a way of representing many different kinds of information and much of this would traditionally be seen as data rather than as documents The Document Object Model DOM connects web pages to scripts or programming languages by representing the structure of a documentsuch as the HTML representing a web pagein memory Why do we need D3 D3 is a popular well established open source framework that runs in most web browsers D3 has a vast assortment of excellent visualization resources support documentation and examples However one of the reasons why D3 is and remains so popular is owing to its flexibility D3 integrates and works seamlessly with web based technologies e g HTML CSSS and SVG including having a large and helpful community of users and developers which is compouned by its accessibility and straighforwardness to learn D3 Features D3 is able to work with a vast assortment of data types to create both simple and complex visualizations These visualizations can also be animated and interactive Customized user experiences and transition effects To list some of the key features Easy to user and get started Free and open source Extremely flexible Supports large datasets Declarative programming Code Reusability Wide variety of curve generating functions Associate data to elements and groups with the html on the web page img src https notebook xbdev net var images blocks jpg style margin 0 width 100 D3 Benefits Since D3 is an open source project written in Javascript it does not requre any plugins In fact the library itself is very compact and small Homepage development https d3js org https d3js org Latest version 2 10 3 License free under BSD Minified size 116 kb Few of the core benefits and the rational behind its development are Modular library download the full library just small pieces depending on your needs Powerful eye catching visualizations stand out from the crowd Enables DOM manipulation controlling web page Easy to extend create basic standard charts visual components Easy to install
