Update: This relates to what is now known as Geogebra classic (https://www.geogebra.org/classic) and is about using Geogebra to draw stats graphs, specifically:
Histograms, Bar Charts, Box plots, Stacked box plots, Cumulative frequency curves, Stem and Leaf diagrams, Bar charts. This goes through my experiences and recommendations for opening geogebra, getting data into geogebra and then a run through the graphs and the various options.
Note: On the scatter graphs, you can actually draw lines of best fit. See the 'Regression model' options underneath the chart.
Update: Starting Geogebra is a little different now. Look for the classic links or try entering /classic in the address bar.
