You can click and drag on connections to wire things together and right click on the wires to change their colours. This view is the one you are used to, building is as simple as searching for the part you are after in the top right search window and dragging it to your design. There is also a code tab which should work just like the Arduino IDE if you want to use it to save, upload and edit in too, but I must admit I haven't tried it. There are 3 views available, the breadboard, schematic and PCB which are all linked. It enables you to build designs for your circuits in a way that is friendly to beginners and many maker suppliers (Adafruit, Sparkfun etc) release components that you can add to the parts library. These are created with a great Open Source bit of software called 'Fritzing' which is free to download, though they deserve a donation if you can afford one. Firstly, you may have been wondering about these lovely circuit design images you have seen here and around the web.
We are going to take a little break from coding and have a look on the tools side of things.
