Deepak G.D3.js Mastery
A comprehensive, ground-up masterclass on data visualization. We abandon wrapper libraries to build complex, highly interactive data experiences using the raw math of D3.js.
Prerequisites
- •Solid foundation in HTML and modern CSS.
- •Strong grasp of JavaScript (ES6+), specifically array methods like
map,filter, andreduce.
Phase 1
The Building Blocks
The foundational physics of Data Visualization.
- Part 01
Part 1: The Canvas & Coordinate System
The Goal:Understanding why D3 exists and the environment it draws in.
The Lesson:We compare D3's declarative approach against Vanilla JS and React. Then, we break down the physics of the SVG Coordinate System, where (0,0) is inextricably tied to the top-left corner.

Part 2: Selections & Appending Elements
The Goal:Mastering how D3 interacts with the DOM.
The Lesson:Learning the fundamental syntax to select elements, append new native SVG nodes, and draw your very first shapes using method chaining.

03. The Dictionary: Domain and Range
The Goal:Translating "Data Language" into "Pixel Language."
The Lesson:Mastering the relationship between your Domain (the min/max of your actual data) and your Range (the width/height of your screen).

04. The Engine: D3 Scales
The Goal:Turning numbers into positions and colors.
The Lesson:Implementing Linear, Band, and Time scales. This is where we use the Math from Post 02 to calculate the exact pixel position of any data point.
- Coming Soon
05. The Bridge: Data Joins and Accessors
The Goal:Binding your array to the DOM.
The Lesson:How D3 accesses each row of data. We will compare datum() for single elements vs. data() for collections, and master the modern .join() pattern to handle the lifecycle of your elements.
