The dynamic use of technology allows very different ways to visualize graphs and mapping diagrams. The most common ways to do this are through the use of animations, interactive sliders, and mouse or keyboard controlled movement of objects without sliders. Examples using these tools to give a 21st century approach to understanding these visualizations will appear throughout this resource .
Though there are several possible platforms for creating dynamic
visualizations, for this introduction to the concepts I will focus
mainly on using GeoGebra. Its advantage is that it is open source
freeware and it supports the three main methods for adding
dynamic features: animation, sliders, and mouse/keyboard
controlled object movement.
