Visualize the comparison of delayed vs not delayed flights using a Pie Chart node

Step 1: Click on the "Pie Chart" node to open the configuration window.

Step 2: Select the category dimension as "delayed" and the aggregation method as "Occurrence count" so that the number of "delayed=YES" and "delayed=NO" flights will be calculated for each section of the donut chart.

Step 3: Select "Apply and Execute".

Visualize the individual column stats using a Data Explorer node

Step 1: Click on the "Data Explorer" node to open the configuration window.

Step 2: In the options menu, specify the title and subtitle for the views and provide additional information if that is necessary.

Step 3: Select "Apply and Execute".
