In the hotel example, what is the common data?
Income Earned
3rd stage in decision making
Adopting a processing language
what are the 2 essential precaution when processing a data and generating the visualization
ensure maximum visual efficacy
ensure mobility of image
How can we ensure mobility of an image when creating a visualization
Make sure that the relationships between different components in a data are charted separately and understandable for the user.
How can we ensure visual efficacy when creating a visualization
Example : color /highlight the months where the hotel earns more that average income
What is the 4th stage in visualization
processing the data ; simplifying without destroying the data
Explain step 4
reclassification,arrange in alphabrtical order etc
What is the 5th stage in visualization?
interpreting results and communicating the data
