Grapholite is a new online service for creating diagrams. Grapholite features a drag and drop interface for creating flowcharts, organization charts, and more. You can create new diagrams from scratch or use the sample templates provided by Grapholite.

If you choose to create from a sample template you can edit the arrangement of elements, rename elements, and edit the colors of elements. To create a diagram from scratch choose “new” from the file menu then begin dragging elements onto your canvas from the menus provided. You can then label the elements of your chart, add colors, resize elements, connect elements, and arrange elements with a simple drag and drop system.

Applications for Education
Grapholite could be used by students to create cause and effect charts, story webs, or perhaps models of elements from the periodic table.
