What is a Riser diagram?
A friend wants to add a shower in the basement. The township is asking for a riser diagram showing all pipe sizing and venting fixtures.
How to draw that, I notice some books have images of a whole house piping. Not sure if that is called riser diagram. Anybody can give a link to show an example?
If you include both supply and drain lines, the drawing will be pretty complicated. Not sure if we can separate these two categories into two plans.
Thank you.

Most times a riser diagram in an already existing structure consists of the placement of existing fixtures in conjunction with the new proposed system.
That new system will be required to have a design that is compliant to local codes.
A diagram of the Drain Waste and Venting system
AND
A diagram of the Water Supply Distribution system
Most diagrams are done by isometric drawings using a 30/60/90 degree triangle to show the layout of your new system.
It is complicated if you've never done it before.

there is a link to a simple riser diagram.
and yes, there is software available for this if you want but for a single house it would be quite expensive and take a bit of learning to make the drawing.
I would simply get out the drafting table, some triangle and a scale and draw one up by hand.

It might be a good idea to clarify with the municipality what they are wanting exactly as well. Maybe call and ask a plans examiner or something if possible.
For example..i've worked in many municipalities in Florida. Some require actual isometric drawings. Some just want a plain old hand written sketch, very basic, just so they have something in the file giving a person in the future an idea of what is there. (a basic stick drawing with arrows showing flow).

When I did a pretty major remodel, the town inspectors office stated they required plumbing drawings. I did my research, and ended up drawing isometric drawings for the supply and DWV systems. I was all proud, handed them in with my $150 charge, and he looked at them and said, "wow, we rarely see drawings like this, even from plumbers". Turns out he was only looking for a "stick" drawing that showed pipe sizes to ensure everything was planned out correctly.
