Here are a series of dynamic graphs for understanding various abstract concepts that are best explained by using visual presentation and motion. Many of them are about using basic economic principals of supply, demand, revenue and profit. To view these graphs you should use the Microsoft Internet Explorer with the Adobe SVG Viewer plug-in installed. You can download one from Adobe by going here.

Finished with Version 1

These dynamic graphs are intended for educational use as reusable learning objects. These the economics graphs all use linear demand curves, which is usually a good approximation to reality over a short range of prices.

1. Price and Quantity How do changes in price affect quantity sold for a standard fixed demand curve? (beginner complexity)
2. Demand Change When people demand more or less of something and the supply is fixed, how does this impact the price and quantity of goods sold? (beginner complexity)
3. Total Revenue How do of price changes impact the Total Revenue (TR=P*Q) for fixed demand? (intermediate complexity)
4. Profit What is the impact of price changes on profit under fixed demand with a fixed marginal cost (MC)? (intermediate complexity)
5. Profit Maximumization Where does profit maximization occur? This dual graph shows that when the slope of the profit curve is zero, profit is maximized. (intermediate complexity)
6. Price Elasticity How do we see price elasticity variations in demand lines? (intermediate complexity)

ToDo

Here are the graphs I have not done yet. Let me know which ones might help out in your classes.

1. Isocost Curves How do you balance inputs to production such as capital and labor? (intermediate)
2. Optimal Input Balancing How do you change the ratio of inputs if your costs changes? (intermediate)
3. Marginal and Average Cost What is the shame of Marginal and Average costs as quantity varies? (intermediate)
4. Short Run Costs What are the shapes of the short term marginal, average and fixed cost curves as Q varies? (intermediate)
5. Long Run Costs What are the shapes of the marginal, average and fixed cost curves as Q varies? (intermediate)
6. Learning Curves How do production costs vary as you gain experience in manufacturing? (beginner complexity)
7. Perfect Markets Demand curves under perfect competition? (intermediate)
8. Monopolistic Competition Demand curves under monopolistic competition? (intermediate)
9. Exponential Growth Curves Systems that are prone to networks effects frequently display exponential curves when they are first being adopted. How can you predict growth rates based on early indicators of exponential growth? (advanced)

The slider object in these examples was take from MecXpert web site.

If you are non-profit organization and would like to use these dynamic graphs in your courses, please feel free to do so but please give me credit for the work I have done. If you do use them and your students like them, please let me know and I will create more of them based on your classroom feedback.

If you are for-profit organization and would like to use these dynamic graphs in your course materials please contact me about using them. I can also create dynamic graphs that are customized for your training needs.

Note: I have not been able to get these to work under FireFox 1.5 (which does have native SVG support) or the Apache Batik viewer. Please let me know if you have any suggestions. I am willing to make small changes for compatibility but not large changes that require significantly more code. To allow others to reuse these dynamic graphs we need to keep them as simple as possible.
