Due to the limitation that Tableau Public can only store a maximum of 15,000,000 rows of data, the only way to publish it on Tableau Public is to use aggregation and it has helped me in aggregating based on the location coordinates and the radiation measurements. Because of this, there are values that can't support the overall view of the analysis. However, the storyboard of all the full analysis and its dashboards are also explained in Tasks Questions and Answers. The interactive storyboard of the aggregated charts can be accessed here: https://public.tableau.com/profile/jim.meng.kok#!/vizhome/IS428_2019-20_G1_Individual_Assignment__KokJimMeng/IndividualAssignmentVAST2019MiniChallenge2

The storyboard aims to provide users with the various dashboards to show the overview of the tasks given by this challenge. Moreover, it has 7 buttons on top to see each dashboard that answers the tasks questions. The followings are the 7 dashboards in the storyboard.

Filters/Interactive Features	Descrption
	It is a filter of the radiation classification of the radiation measurement in CPM where: 1. Deviation: 0 to 11 CPM 2. Anomaly: 12 to 24 CPM 3. Incident: 25 to 49 CPM 4. Serious Incident: 50 to 59 CPM 5. Accident with local consequences: 60 to 99 CPM 6. Accident with wider consequences: 100 to 149 CPM 7. Serious Accident: 150 to 499 CPM 8. Major Accident: More than or equal to 500 CPM
	Choose the sensor type based on this filter.
	To see the animated path of the mobile sensors. To play forward, click the right triangle. To play backward, click the left triangle. To pause, click square. Based on the speed, 1x is the 1-bar, 2x is 2-bar, and 3x is 3-bar.
	Select the day of the timestamp where the number is the day of the date.
	Select the sensors based on its ID where M-XX is Mobile Sensor and S-XX is Static Sensor.
