User selects two or more representation attributes for scatter plot (or bubble chart) visualisation

[tmfrnz]

As a user

I want to select the two attributes of the tsunami records (all or subset) for the x- and y-axes of the scatter plot

so I can get a better understanding of the data

Can we do more than TWO?? I think options to tray several would be good - this may not work all of the time but would give the user (whoever they were) some flexibility

Scatter plot requires at least 2 attributes that ideally the user can freely select

• x-axis attribute, eg time, magnitude, etc,
• y-axis attribute, eg landward limit, source region type

In addition the dot could be visualised to represent one or more additional attributes, effectively making it a bubble chart) options include

• marker size
• marker colour
• marker shape
  (similar to map attributes: User selects color attribute for map visualisation #4, User selects size attribute for map visualisation #5)

This would effectively be a re-implementation of the famous GapMinder:
