Basic Charts – Part 1
This Tableau file contains information on all U.S. airline flights from 2010 and 2011. Create a Tableau worksheet to answer each of the following questions:
FILE to use: your completed Flights_data.twbx
1. A quick viz of flights over time shows a drop of more than 300,000 flights from 2010 to 2011:
From your experience, you know that flight activity did not drop so significantly between 2010 and 2011. Why does this viz seem to indicate otherwise? Investigate flights over time in more detail to determine why these yearly numbers show such a large drop.
2. You are interested in identifying days that are particularly light in terms of travel each year. Are there particular holidays that seem to experience substantially lower numbers of flights?
3. Next, you want to know who operates the most flights. Is there one airline that operated more flights than any other single airline for each week in this dataset?
4. You would also like to know which states tend to experience the longest departure delays. Create a map that visualizes the departure delay that you can expect in each origin state. Allow the user to filter by airline. Colors should range from dark blue for states with short departure delays to dark red for states with long departure delays.
Dashboards – Part 2
As a starting point for this exercise, use the visualizations you created in Part 1 using the Flights Data. Organize those worksheets into the dashboard depicted below (try to recreate it exactly). Note that a selection on the right updates both the map and the line graph.
