In economics, a demand curve is a graphical representation of the connection between product price and quantity demanded.
To know about what change is made in the graph we first need to go through the concept of the demand curve.
What is the rightward and leftward shift in the demand curve?
When compared to the original demand curve, a rightward change in demand would increase the quantity required at all prices.
A left shift suggests a drop in demand, whereas a right shift shows an increase in demand.
Thus, in the above graph, there is a rightward shift of the demand curve from left to right (D1 to D2), indicating that demand has increased.
