The most widely used data visualisation techniques are:
-
plot: plot the relationship of two dimensions of the record;
-
histogram: data values control the height of rectangular bars;
-
web: show the strength of connection between values of two
or more symbolic fields;
-
pie or bar graph: use the area of the pie or hight of the
bar to show the ratio of different kinds of data.
-
tree visualiser: visually manipulate and explore the decision tree.
The interactive techniques can be combined with these visualisation techniques to form data
analysis tools.
