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.

## Problem statement 
The tasks in this challenge are as follows:
- Select a suitable scale for a given task.
- Map different courses to specific timings using a selected scale.

## Given data

We have four courses that will be mapped to four timings.

```
courses=['History','Mathematics','Philosophy','Computer Science']
timings=['8-9','9-10','11-12','12-13']
```
## Expected output

If we give `History` as input to the scale, it should give `8-9` as output. For example:

```
console.log(c_scale('Mathematics'))
``` 
It should show `9-10` on the console screen, where `c_scale` is the scale created by the user.
## Coding exercise
This problem is designed to check your understanding, so you are encouraged to solve it on your own. If you are completely stuck then refer to the next lesson which will explain the solution in detail.
