Density 2D Chart Angular & D3.js
Welcome to the D3.js Angular graph gallery: a collection of simple charts made with d3.js & angular created by LAAKISSI Achraf. D3.js is a JavaScript library for manipulating documents based on data. This gallery of a few graphics, always providing reproducible and editable source code. If you are new to creating graphics with Angular & D3.js, this is probably the place to start.
This post describes how to build a 2d density chart using angular & d3.js. we’ve built a component you just need to add to your project, passing the input data, specifying other options and you get your chart easily. you can find the code on our website or in stackblitz.
A 2d density chart displays the relationship between 2 numeric variables. One is represented on the X axis, the other on the Y axis, like for a scatterplot. Then, the number of observations within a particular area of the 2D space is counted and represented by a color gradient.
The 2d density chart is made thanks to the d3-contour plugin.
The input dataset has 2 numeric variables: x and y. A 2d density plot basically represents the amount of data point on each part of the grid.
Component inputs :
- data: It is an array of objects (dataset), each object contains 2 numeric variables: x and y
- colorsInput: It is an array of 2 hex color codes.
