Building Interactive Data Visualizations with D3.js

Getting Started 4 lectures 22:11 The Course Overview This video will offer the overview of the course. Downloading D3.js and Getting the Server Running For much of D3's functionality, a web server is necessary for both developing and serving. We will get a simple HTTP server running to test and serve D3.js pages.

• Download D3.js from d3js.org
• Create a boilerplate HTML page
• Use Python to run a simple HTTP server to view our hello world example in the browser

Console to the Rescue Debugging web applications can be complicated as one often needs to know the values of variables at certain times of execution. We can use console.log() to print statements to the browser's console to explore the changing state of our programs.

• Activate the console
• Explore how JavaScript represents the HTML page in the DOM (Document Object Model) with nodes and elements
• Print debugging statements to the console

Raw JavaScript Versus D3.js The main functionality of D3.js is to manipulate the DOM (Document Object Model). So, we learn how to select elements and manipulate their styles and attributes both with low-level JavaScript and higher-level D3.js functions.

• Select an element in an HTML page and add text to it, both in standard JavaScript and using the D3.js functionality
• Set an attribute and the style of the selected HTML element using standard JavaScript and the D3.js functionality
• Change the style of a group of elements using both standard JavaScript and D3.js

Raw JavaScript Versus D3.js The main functionality of D3.js is to manipulate the DOM (Document Object Model). So, we learn how to select elements and manipulate their styles and attributes both with low-level JavaScript and higher-level D3.js functions.

• Select an element in an HTML page and add text to it, both in standard JavaScript and using the D3.js functionality
• Set an attribute and the style of the selected HTML element using standard JavaScript and the D3.js functionality
• Change the style of a group of elements using both standard JavaScript and D3.js

Binding Data to HTML Elements 3 lectures 17:08 Planning Our Page It's important to plan out how you expect your page to look and behave before you start to code it. We'll take a look at what our intentions are and plan accordingly.

• Plan out the look of our page
• Think about and build a mock-up of our data structure
• Use D3's selectAll/enter paradigm to generate an initial skeleton of the page structure

Entering Our Data It's a good practice to use static data before appending new elements to the page to help understand how your page will look. We do this by pasting multiple copies of the same static elements to test our design.

• Mock up our page
• Add CSS styles
• Once our layout design is complete, use our data to create elements, text, and attributes

Dynamic Color Range Color is an effective means of quickly representing data. We apply this to our dataset by color-coding our "ease of use" variable.

• Learn about D3's scales
• Create a dynamic color scale based on our data
• Create a legend for easier comprehension of our data
