Most  projects start with some sort of brainstorming meeting in which the members of the new project group get together to discuss what the new project is, how it is going to work, what has to be done to carry it out etc. 

(The number of activities and elements is kept intentionally very low in order to improve the clarity  of the explanation.)

Relationships between two elements can be represented using colored arrows. Different types of relationships use different colors.

Either the project leader decides who does what, or the members of the project volunteer:

So the aspect "Who" has been added to the original 2-dimensional view.

The activities can be put on a time line. 

The first view can be made more easily understood by using colors:

Here all the details of the elements are shown, and a color scheme improves the user's ability to recognise details at a glance. (The  aspects "URL" and "Hours" have been added as well.)
