Gain insights into D3.js fundamentals, explore DOM manipulation, data binding, and SVG. Learn about creating maps, graphs, and network visualizations to master data-driven documentation.

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

var mydata=["London","New york","Paris"]
d3.select("body") // Creating three h1 tags using append function.
  .append("h1")
d3.select("body")
  .append("h1")
d3.select("body")
  .append("h1")    
d3.select("body") // Binding data mydata elements with h1 tags
  .selectAll("h1")
  .data(mydata)
  .text(function(d) { return d;})

## Explanation
Let's discuss the above code to better understand how it works.
- From **line 3** to **line 8**, we are appending three `h1` tags inside the `body` tag using the `append()` function. 

- In **line 9** and **line 10**, we are selecting the all `h1` tags inside the `body` tag.

- In **line 11**, we are mapping every single data element to the selected `h1` tag.

- In **line 12**, we are associating text with `h1` tags based on its mapping with the `mydata` array.
