Introduction to Visualization Using D3.js.png

In this course, you will learn the fundamentals of D3.js (stands for Data-Driven Documents), which is a JavaScript library mainly used for visualization.

In the first half of the course, you will cover DOM (Document Object Model) manipulation, method chaining, data binding, and data loading.

In the second half, you’ll cover visualization concepts and dive deep into SVG which is used to draw different geometrical shapes. After that, you’ll work with various maps and graphs in order to display your data. Lastly, you’ll learn about network visualization with the help of nodes and links.

By the end of this course, you will have a new, powerful data visualization library at your disposal.

Introduction to Visualization Using D3.js

## Introduction
After exploring the steps needed to draw a pie chart in the previous two lessons, it is time to dive into creating a pie chart. A pie chart is used to show the proportion of different quantities. We will draw a pie chart in D3.js with the help of the following two APIs.
- `d3.arc()`
- `d3.pie()`

## Example
Let's demonstrate the pie chart by taking some dummy data that shows programming languages used by developers in 2020.
