Hexagonal Binning

Example of hexbin by Mike Bostock

There are many levels that we can consider when thinking of how to analyze the intensity of energy consumption in Singapore, such as on a national level, regional level, or subzone level. But these levels are too coarse and does not provide a comprehensive view - for instance, a large subzone would surely have a higher energy consumption level since there are more residents living in it.

Thus, to properly analyze the intensity of energy consumption in Singapore, we need to do so on a more granular level; We decide to break down Singapore into various groups of postal codes. By aggregating a few postal codes together, we have a higher chance of uncovering new findings.

The best way to visualize this would be to plot hexagonal bins (“hexbin”) onto the Singapore map, with each hexbin representing a group of postal codes, and using a gradient colour scheme to represent each group’s energy consumption intensity.

Line Chart

Example of line charts by Mike Bostock

We will add in a multi-series line chart to allow users to compare the monthly energy consumption levels by: 1) entire Singapore, 2) a group of postal codes, and 3) each postal code.

The default line chart would show only the average monthly consumption of the entire nation. Upon clicking on a single hexbin, the line chart would populate another series to show the average monthly consumption by the group of postal codes within that hexbin. Finally, a third series representing a single postal code would be displayed when ...
