| |
| − |
| |
| − | * Digitizing of each chain’s trade and delivery area
| |
| − | * Business profiling of the company’s outlet to determine Points-Of-Interests that can generate insights such as: Highest earning outlets, relative performance of outlets, outlet’s profile patterns and item sales information.
| |
| − | * Allow for informed business decisions, such as determining locations for new outlet openings with matching POIs of high sales outlets
| |

| − | The visualization provides the buffer polygons, as well as representing population density of the area through colour. By comparing the two, we can conclude whether the center of activity is proportional to the population density in a region. It allows us to perform further exploration to see what spatial information significantly affects the level of activity in a city, such as the availability of points-of-interest. This visualization is great as it allows the viewer to clearly see multiple dimensions dealing with spatial data in an elegant way.

| − | The graph on the left shows the distribution of outlets on the geographical map. The right graph describes the outlets grid distribution, result from grid creation and spatial joint operation. From both figures, they can show the potential tendency of whether the outlets are clustered, and with the number of outlets in each grid. We could use them together to justify and adjust the outlet locations.

| − | This shows kernel density surface, based on the number of fast food restaurants around Jakarta and distribute them smoothly, so it provides average surface estimation. Kernel density estimation allows us to observe both the centrality and agglomeration of existing outlets. This visualization allows us to view multiple dimensions at a time in an effective manner, through the choice of colour and size.

| |
| − | ||
| |
| − | The adopted process was having clear instructions issued to each member in the team, along with maintaining constant communication with each other. In the event that the dataset is deemed too dirty to be usable, it was dropped along with sourcing for new data that would be a suitable replacement.
