Supply and Demand Curve Chart

A clean editorial economics chart illustrating supply and demand curves on a crisp white background. Two intersecting curves drawn in thick strokes: a downward-sloping demand curve in deep cobalt and an upward-sloping supply curve in warm terracotta. The intersection point is marked with a large filled circle labeled "Equilibrium" with price (P*) and quantity (Q*) dashed lines extending to both axes. Two scenario arrows: a rightward demand shift labeled "Demand increases →" and a leftward supply shift labeled "Supply decreases ←". Axes in heavy black with "Price" on Y and "Quantity" on X. Callout box in pale gold: "When supply falls and demand rises simultaneously, prices surge faster than either force alone would cause." Grid in faint 10% grey. Title in a confident serif at top-left.
