Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Create a new Power BI Desktop file, and load a list of the world's tallest buildings from Skyscraper Centre.  You can get a link to the relevant website at this page.

If you don't have Internet access you can use the CSV file in the above folder, but it might not be as much fun!

Add steps to your query so that it creates results like this:

Table of skyscrapers

We've lost the height in feet and some other columns, and split the city into City and Country. 

Create a chart comparing the number of skyscrapers for each country:

Number of tall buildings by country

The number of buildings for each country.

 

Apply a filter to the visualisation within Power BI Desktop itself to show only countries having 5 or more skyscrapers:

Top 3 countries

United Arab Emirates, China and the US, if you're wondering ...

 

Save this file as Skyscrapers, and close down the Power BI instance that created it.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
