I have Visio 2013 Standard on my computer. It comes with 15 templates but not the Basic Flowchart template. How can I access the Visio 2013 Basic Flowchart template?
To start with the Basic Flowchart template, open the Visio application and then double click the Flowchart category and the Basic Flowchart will be shown on screen.
This is also the way Microsoft recommends doing it on their support page that has been created especially for this particular job.
