fmisc,
The top chart shows the sign and degree of the planets and what house each one is in. The bottom chart shows the sign and degree of the house cusps (a "house cusp" is the sign on the edge of a house). Since there are many different house systems used to divide up a chart the bottom chart indicates it is using the "Placidus" method of house division. While both charts have important information it is far more useful to have a graphic of an actual birth chart when doing a chart interpretation.
Astro-simply,
