D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. This course helps you know about the concepts — selections, data joins, interpolation, generators and a lot more.
Upon successful completion of the course, the learner will be able to
Manipulate DOM elements with respect to data.
Create event driven models built on data.
Dynamically update models and charts with respect to data.
Build customized charts.
In Introduction to D3, you will have better information about D3, Selections, Events and Data Joins.Selections allow powerful data-driven transformation of the document object model.D3 also supports built-in events and custom events.Data Joins works along with selections and enables us to manipulate the HTML document with respect to our data set.
An Array contains a fixed-size sequential collection of elements of the same type. In Array API, you will get exposure about iterable manipulation while analyzing or visualizing data. A collection is simply an object that groups multiple elements into a single unit. The d3-color API provides representations for various colors. You can perform conversion and manipulation operations in API.
A delimiter is a unique character or series of characters that indicates the beginning or end of a specific statement, string or function body set. Delimiter-Separated Values provides a parser and formatter for delimiter-separated values, most commonly comma-separated values (CSV) or tab-separated values (TSV).
Interpolation is a method of constructing new data points within the range of a discrete set of known data points. Interpolate API provides a variety of interpolation methods for blending between two values like numbers, colors, strings, arrays, or even deeply-nested objects. For better visualizations D3 provides Number Format and Time Format.
A polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. Polygon API provides a few basic geometric operations for two-dimensional polygons. A scale is a function used to map data from an input domain to an output range. When making a chart with D3, you will often need to convert values from the data to a pixel location or length within an SVG or canvas.
SVG is an image that is text-based. SVG has a number of built-in simple shapes, such as axis-aligned rectangles and circles. For greater flexibility, you can use SVG's path element in conjunction with D3's path data generators. All SVG shapes can be transformed using the transform attribute.
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. Animation is nothing but a transition from one form to another.
A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture or material composition. Visualisations typically consist of discrete graphical marks, such as symbols, arcs, lines and areas.
A chart is a graphical representation of data, in which "the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart".Charts can display a lot of information is an easy to understand format. Using D3, you can bring data to life.
