A schematic diagram would be an infinitely long straight line. Unfortunately, you cannot draw an infinitely long line - the universe is just not big enough!
A tangent is an infinitely long straight line.
"As the crow flies" means a straight line distance between two points, and that would mean flying. There are several web sites on line, that will calculate the flight distance for you, as long as you input the origin and the destination.
On a straight line, those would be some 3,200 Km (1,989 miles)
take the rule and draw a line that is as long as you need it

4500km in a straight line
If you could do it in a perfectly straight line,it would take 5,470.6 hours or 227.9 days.
Approx. 7 500 km (straight line).
