Make the graph move. See why the answer changes.
Press play once. Indirect Tax builds from the first market to the final welfare effect without making you work through the controls.
No signup. It plays on its own.
The missing piece
A finished diagram shows the answer. It leaves out the change.
The hard part is knowing what moved, why it moved, and what follows. Graphacon puts the explanation beside the movement, one step at a time.
- 01A tax raises cost
Start with the cause instead of copying the final picture.
- 02Supply moves up
Move the curve and see the tax wedge form.
- 03Price and quantity settle
Read the new equilibrium from the graph.
- 04The explanation follows

FAQs
Is the free version a limited teaser?
No. Indirect Tax, Elasticity, and PPF are complete modules and remain free.
Is this a subscription?
No. The founding pass is one payment and nothing renews automatically.
Does it work on a phone?
Yes. Graphacon is a website designed for phone use. It can also be saved to a home screen for quick access.
Which exam board is it for?
Any of them. A supply and demand diagram is the same picture whichever board you sit, so the lessons keep to the wording all of them accept rather than one board's house style. Graphacon is independent and is not endorsed by any exam board.
Is every planned graph already available?
No. The current library has 16+ interactive graphs, and new graphs are added regularly.
