Introduction Page

To help users navigate around the dataset better, I have segregated the dataset into multiple visualization to display different insights. To start off, user will first be greeted by the Introduction page as show above, which helps to give a brief problem statement and objectives. Lastly, it will also display 4 buttons to navigate to the following visualization:

1. Overview by Town – Allow users to see the radiation reading by town according the time they filter by
2. Overview by Sensor - Allow users to see the radiation reading by sensors according the time they filter by
3. Detailed Overview of Ind. Sensors - Allow users to check on the fluctuations of individual sensors
4. Movement of Mobile Sensors – Allow uses to see how the mobile sensors (cars) move around the town and potentially spread the radiation if contaminated

Overview by Town Page

This visualization aims to show users the radiation reading/contamination level of individual town at different point of the day

Features	Rationale	Brief Implementation Steps
Filter by Timestamp	Allow users to set the timestamp to check the radiation readings at that point of time	Drag Timestamp to filter pane Choose Individual Dates and Times as the filter Right click the Timestamp on filter pane and set Show Filter to be True Choose Single Value (slider) for the filter function

Overview by Sensors

This visualization aims to show users the radiation levels based on all of the sensors spread across the map and can filter by time and sensor type.

Features	Rationale	Brief Implementation Steps
Filter by Timestamp	Allow users to set the timestamp to check the radiation readings at that point of time	Drag Timestamp to filter pane Choose Individual Dates and Times as the filter Right click the Timestamp on filter pane and set Show Filter to be True Choose Single Value (slider) for the filter function
Filter by SensorType	Allow users to filter to see only the sensor type they want to see	First create Group among the sensor id in terms of their type (static/mobile) Drag the newly created group to the filter pane

Detailed Overview of Ind. Sensors

This visualization aims to give the users a more in-depth understandings of the data captured in individual sensors and analyze its fluctuations over the 5 days.

Features	Rationale	Brief Implementation Steps
Filter by SensorType	Allow users to filter to see only the sensor type they want to see	First create Group among the sensor id in terms of their type (static/mobile) Drag the newly created group to the filter pane

Movement of Mobile Sensors

This visualization helps to illustrate the movements of mobile sensors. As there is possibility of contamination outspread due to the sensors’ movement, it will be beneficial to be able to track the movements over the 5 days.

Features	Rationale	Brief Implementation Steps
Filter by Timestamp	Allow users to set the timestamp to check the radiation readings at that point of time	Drag Timestamp to filter pane Choose Individual Dates and Times as the filter Right click the Timestamp on filter pane and set Show Filter to be True Choose Single Value (slider) for the filter function
