Graphite

Graphite is an editor for flowchart-like diagrams.

More technically explained:
Graphite is an application for creating and editing of graphs. The term graph means here a set of nodes and edges, whereby each edge is connected to two nodes.
This definition might be not very clear for someone, who is not familiar with the term graph. So here is second definition:
Graphically (no pun intended) a graph consists of some boxes with text in it (the nodes) and some arrows (the edges), that go from one box to another.
This gives a widely used type of diagram, that you normally would produce with an application like Draw or Artworks. Indeed Graphite is in some way similar to Draw.
But while in Draw you operate on plain graphical objects, in Graphite you operate on nodes and edges. This is a different level of abstraction and it has the consequence, that you don't have to care about certain things, you would need to do manually in Draw:

If you move a node around, the connected edges follow the box automatically.
If you create a new edge, it is guided automatically around existing nodes (so it doesn't cross any node).
If you move a node to a position, that is already occupied by an edge, the edge moves away automatically.
If you want to change some edge-effects (width, colour or something like that) for the whole document you can do this easily, because Graphite knows the difference between a line that forms the edge and a line that forms the border of a node. In Draw both would be simply a line, so you would need to select the edges manually.
Likewise you can change some node-effects without effecting the edges.

Furthermore Graphite provides the features you would normally expect from a RISC OS application:

editing of multiple documents
multiple views of the same document
unlimited undo and redo
... and a lot more

Graphite is compatible with RISC OS 3.5 or higher. Graphite is 32-bit compatible now.

At present there is only a beta version of Graphite available for download. It seems pretty stable, but it is still a beta version and has its limitations (a lot of umimplemented features, some minor bugs and a few more serious bugs).
