 ### Context
 In the Mode editor, go to 'Report Builder', then to 'Edit HTML'. Here you can add custom HTML, CSS, and javascript to your dashboard. A global variable called ```datasets``` is available to any Javascript function, and it contains the results of all your queries. How your results are stored in this data structure is a little wonky, but the functions in this repo abstract all that away. However, be aware that if your results take up more than 15MB of space, then this object will point to a .csv file instead of as a JSON, and none of these tools will work.

 ### Step 1: Write a Query
 Write a query that has a 'lat' and 'lng' column, or a 'geohash' and 'value' column. The columns do not have to be named these, they just have to represent the lat/lng pairs or the geohash/value pairs you want to plot. Run your queries.

It should look like ```radius_fun(content, idx)```, where content is the table associated with ```query_name``` and ```idx``` is the index in ```content``` currently being plotted. Note you can call on any column in ```content``` to determine the radius. If ```radius_fun = null``` then the radius is 2px.

+###Built-in Color Functions
 There are a few color function generators already built in to ```modemap```. More to come!
 
 1. ```modemap.color.fun.constant(color)```: takes a color (hex string) and returns a function that will return that color for all plot markers. 
 2. ```modemap.color.fun.jet(val_col, min_val, max_val)```: takes the name of a value column in your query results, ```val_col``` and returns a function that will return a color according to [JET](http://matlab.izmiran.ru/help/techdoc/ref/colormap.html) linear color scheme. Values less than ```min_val``` will be assigned the lowest color value (blue) and values higher than ```max_val``` will be assigned the highest color value (red).
