DoCircuits is an interesting as well as learning circuit design and simulation tool.
I bet you will like its function, especially graphics, i.e. unlike other tools, when you connect a component (say a bulb) in the circuit, you will see a bulb icon instead of symbols. With the help of this tool, you can build, run simulation, and analyze both electrical and electronics engineering (Digital and analog) circuits very easily and export your file as PNG. It also provides DC analyses, Time and frequency domain analysis with accuracy output level.
It is also free and doesn’t need to be installed in your computer. So don’t wait. Just give a try to DoCircuit because it is a web-based, i.e. online circuit design, simulation and analyzing tool.
Update: The official website URL of DoCircuits is offline at the moment. You can download the older version from Google.
