I've only really got to grips with the sign depositor wheels,to me it seems like the most important thing to focus on.the others are important too in other way but I think they need to be interpretted differently.

 

I think on the astro site there is a very good explanation on how each different chart works and help on how to read them.

 

From the sign depositor wheel looking at Neptune its energy goes through Venus as its in Libra but we also remember that it interacts with the aspected planets in the natal. With Neptune in the 4th in libra I would imagine you would wish for a very pleasant home and family life and a calm and balanced environment.Venus then deposits to Jupiter and Jupiter then to Pluto,Jupiter is interestiung as its quite close to Venus and makes some similar aspects to Venus,I often think of jupiter as an amplifier,like if for example (hypotheticly speaking) Venus was a song then Jupiter is the marshall rock amp to crank up the sound abit more! when Jupiter is in the mix it tends to put abit more umphh! on what its interacting with. I think Pluto is also very important as it too is in Leo adding more weight to this sign as being an important sign in your chart.
