Tableau visualizations

I need for the flights delay dataset to have One Dashboard by combining 2 visualizations.
Two other unique visualizations are also required, These can be two single worksheets, two more dashboards, two more stories, or any combintation of worksheet, dahsboard, or story.

so total is 3 insights as 1 dashboard and 2 visualization graphs to answer 3 questions for interesting insights like:
1- which airport has the worst flight delays?
2- which airline has the most cancelations?
3- what are the common reasons for flight delays?

So I'll need the steps on tableau public so I can follw it and create it to my own profile.
