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

## Summary
In this course, we took a beginner-level look at D3.js for data visualization.
- In Chapter 2, we started with the fundamentals of D3.js, which include DOM manipulation and data binding.
- In Chapter 3, we began with scales, where we learned about different types of scales and how to draw them in D3.js.
- In Chapter 4, we learned about some basic shapes, transformations, and transitions.
- In Chapter 5, we began with data visualization and learned about different charts and how to draw them in D3.js.
- In Chapter 6, we learned about nodes and links and how to use them to draw networks, what hierarchical data is, how to show it through treemaps, and how to add interactivity to data visualization.

## Advanced topics for further study
With the current knowledge of D3.js that you have gained through this course, you can show data with appropriate visualization tools. However, there are some advanced topics that you can explore next:
- Choropleth maps to visualize geographical data
- Interpolators, which are used to interpolate numbers, colors, strings, arrays, objects
- Brushes that select one or two-dimensional regions using the mouse
- Quadtrees, which are two-dimensional recursive spatial subdivisions and are used to detect collisions and computing  N-body forces

## Concluding note
