If you have a tablet or smartphone, you might search its app store for an app that displays chords and scales. Some of them also have versions for your laptop or desktop computer. Following is one of the ones I use:
Piano Companion is a flexible chord and scale dictionary with user libraries and a reverse mode, circle of fifths, chord progression builder.

I believe the app is "free+" so you can use it indefinitely for free but will only get access to the more common chords and scales; if you want to "unlock" all of the chords and scales that it covers, they want you to buy the app.
There are a number of other similar apps, but that's the one I use most often.
