30 Days of Maps Day 24 - Only Circular Shapes

Day 24 of the #30DayMapChallenge and today's theme is "Only Circular Shapes" - Map using only circles. Everything should be circular. Forget straight lines and sharp edges, and see how creative you can get by sticking to round shapes.

Today seemed liked a good opportunity to explain the three different options we have in Icon Map Pro for determining circle size.

In the top of the Circle Configuration settings, you'll find a setting called Size Behaviour. This has three options:

1. Relative
   This option provides two further settings, minimum size & maximum size. This will plot all of your circles on the map with their size in pixels between these two values. The size will be determined based on the value in the "Circle Size" field. The smallest value is mapped to the "minimum size" and the largest to the "maximum size", with all other values being calculated in between.
2. Size in Pixels
   Similar to the option above, this option draws circles based on a size in pixels, but rather than being based on a range of values, it uses the specific value supplied in the "Circle Size" field. Therefore if you provide the value 50, it will draw a circle with a radius of 50. As the circle is drawn as pixels, when you zoom in or out of the map, the circle will always stay that size on the screen. This means when you zoom out, it covers more landmass.
3. Size in Meters
   Rather than drawing a circle in pixels, this option uses the value in the "Circle Size" field to draw the circle radius in meters. This means that when you zoom in on the map, the circle appears to get bigger on the screen, but covers the same amount of land. This is a useful option if you wanted to show all points within 5km of a store.
