Lucky for us, the National Center for Education Statistics has a kids section. More specifically, the kids section of the site has a great chart/graph creator that both adults and children will find useful.
The NCES Kids Zone “Create a Graph” center makes creating simple or even complicated graphs very painless. The Create a Graph service enables the creation of bar, line, area, pie, and XY graphs. After selecting the type of graph to make, the simple tabbed layout leads the user through each step of the graph creation process. These steps include design, data, labels, preview, and print/save. The graphs are very customizable, allowing for different backgrounds, 2D and 3D graphs, different shapes, and different legend locations. The color and font associated with each label can be changed as well.
After the perfect graph is created, the Create a Graph service lets users print or download the graph in many formats, or email the graph to others. This handy and dead simple tool will help you at some point, and best of all, it is completely free and requires no registration of any kind.
