project for learning D3

Here you can see how does the visualization look like.

This project is to help me learn D3, a Javascript package for building interactive data visualization. The content is from the course Information Visualization bundle at Courseralink.

The goal of the data visualization project is to create an interactive dashboard with two charts, with one being a horizontal bar chart showcasing number of flights of each flight company, and another being a geographical map showing the network between each pair of destination and arrival airports.

The project contains four steps, corresponding to four week lessons from the online course.

Step 1 Scaffolding the dashboard with a title and two charts

Step 2 Preparing the data and building the bar chart

Step 3 Drawing the map and airports

Step 4 Drawing network and adding hover interaction
