Conclusion
One way to give animation to a geographical map image is to put images of different presentations in layers. To animate, change the position of the layers. Producing a blinking (toggling) effect is a delicate process. In the second example, there were two functions for each clickable region. Browsers today do not have features for animating clickable regions in image-maps.
This is a delicate tutorial. That is why I have given two functions for each clickable region. If I did not do this, you would have found the article difficult to understand. Commercial web pages would have many clickable regions, so having two functions for each region would take up too much space. Now that you understand what to do, you can decide whether to have only two functions for all the clickable regions. You will have to use variables (IDs) to identify the different clickable regions.
Also note that the AREA elements for the images with colored regions each have the onmouseover event. Logically, this is not necessary. However, I have included it because of browser limitations.
