4 Stage 1: Observations from data exploration

As part of the data exploration developed distinct visualizations in Tableau some of the key observations were that there existed a total of 5,159,847 violations captured through the speed cameras between 2014 to present (at the time of data collection). Although the violations are declining crosswise over time, the violations across month are fluctuating. The violations captured across the cameras in different locations and positions vary significantly, and certain areas have higher violations recorded consistently.

Learnings gained after this stage of the project by self-critiquing the visualizations.

• With the intended audience in mind, visualizations must be self-exploratory and straightforward and must involve less effort.

• Use of additional colors to be avoided.

• Use of complex visualizations to convey a simple message to be avoided.

• Beautification of the visualization with the attractive features of the tableau to be resisted.
