The D3.JS, being the successor of the Protovis framework, produces dynamic graphics and interactive data visualizations for web browsers. However, before its development, many attempts have been made in terms of graphical libraries e.g. Prefuse, Protovis toolkits, and Flare. So, all of the features of previously described libraries exists together in form of D3.JS.
History of D3. Js as first leading Graphical library
Tempting and graphical Features of D3. JS
Being combo of the previously designed library, D3. JS functions through Cascading Style Sheets (CSS), HTML5 and Scalable Vector Graphics (SVG). Hence, the multiple vector graphics mode visualizes 3D images for astonishing data Visualization. Thus, the most distinguishing feature of the library is the utilization of pre-built functions for selection of elements, creation of SVG objects, the addition of transitions and interactive effects for web browsers. However, the data visualization in various formats e.g. comma-separated values (CSV) and JSON helps in the creation of 3D images or diagrams. Moreover, the other features which enhance its demands among web designers include:
Selection of CSS style
Declaration of Transitions
Time to time modification of web browsers requires some astonishing graphical styles, which styles and attributes upload it. Hence, the declaration of transitions is crucial for gradual change in textures and designs.
Appending nodes using data
While designing a web browser, the web developers restrict or bound a dataset, whose changes are not possible. But, D3. JS is only one tool that allows the updating of a dataset by explicating the functions. Thus, the commands of enter () and exit () update the dataset, represented by the DOM node in the selection.
Functions of API structure of D3. JS
API structure of D3. JS provides a variety of functions through logical units. These units of API include;
- Colour: the color of background and texture is a major component of designing, and is controlled by API structure as it supports RGB, HCL, and HSL. Hence, it also controls brightening, combinations, and darkening of colors.
- Geometry: the geometry of shapes and structures, and its modification become possible through the API structure of D3. JS. As it computes the intersection of convex shapes and Voronoi diagrams.
Either there is the insertion of elements or CSS styles for updating web browsers, D3. JS is the best graphical library. This library work on the principles of 3 previously designed libraries. So, it has a wide range of features and functionalities for the facilitation of web designers for data visualization on multiple web browsers.
