Is this a good example of aperture, shutter speed, and ISO?

3. It's a great chart for a beginner

What the chart is showing you is what effect you can expect from changing each one of those three exposure parameters.

Any change to one of those parameters will effect one or both of the other two assuming exposure is correct in both instances. All three of those parameters are expressed in 1 stop increments. So in other words if f/16, 1/125, and ISO 100 gives you a correct exposure, but you want a faster shutter speed to freeze high speed action, you can move the shutter speed to 1/500 (two stops), but since the shutter is now staying open for less amount of time, less light is reaching the media. So you'll need to compensate by moving the Aperture two stops to the right, ISO two stops to the right, or both 1 stop to the right.

Another thing that's good to know is the depth of field shown on the Aperture scale is also dependent on focal length and distance to subject. Modern lenses typically don't have depth of field markings, so it's good to have a smartphone app that tells you the depth of field for a given camera/focal length/aperture, and distance.
