Through visual exploration, we noted that “Downtown” and “Uptown” have the highest number of individuals which posted microblogs of them feeling unwell. Drilling further down to the individual grids, most of the concentrated area were Grid 229, 231, 206. On these grids on the map, there were the following landmarks "Convention Centre", "Vastapolis Hospital" and "Vastapolis Dome" | Through visual exploration, we noted that “Downtown” and “Uptown” have the highest number of individuals which posted microblogs of them feeling unwell.

Findings 1
Each square (grid) on the treemap and Area Heat Map represents approximately 1km^2. This is made possible by adding a calculation in Tableau where the population for each area is divided by the total number of grid. Table shown in Image 1 below.
Image1
Through visual exploration, we noted that “Downtown” and “Uptown” have the highest number of individuals which posted microblogs of them feeling unwell. Drilling further down to the individual grids, most of the concentrated area were Grid 229, 231, 206. On these grids on the map, there were the following landmarks "Convention Centre", "Vastapolis Hospital" and "Vastapolis Dome"
Image 2 is the selection done to realised the above. Treemap grid selected. The corresponding grid highlighted in Area heatmap
Findings 2
We then move on to time viz. The question that we want to try to get an answer to is, the high concentration of messages in these 2 areas was it due to accumulation over time? Or was there a particular day which resulted in these large number of messages. Please refer to Image 3. On the overall, we noticed a spike on 18th to 20th.

We removed these 3 dates on the slider to observe any other trends we have not been aware of. Now refer to image 4 for the result on the viz. What we noticed are:
- Downtown and Uptown were higher than average of entire Smartpolis
- No outright trend noticed. However every area seems to fluctuate a lot around their average.
