Until now you've only been able to select connections based on the field values assigned to those connections (things like connection type, strength, etc.). With the new :from( ) and :to( ) pseudo selectors you can now select connections based on properties of the elements those connections are attached to.
A few examples:
- You could select all connections that are coming from elements with type "organization"
:from(organization). - You could select all connections pointing to a specific element
:to(#my-element-label). - Or all connections (from and to) elements that are highly influential
:from(["level of influence"="high:]),:to(["level of influence"="high:]).
To build your own, just add any selector within the parentheses :from(selector). Try building your own by picking an element from your map ("Advocacy of Public Unions") and then using it in a selector in the search by typing =:to(#advocacy-of-public-unions).
Using focus to identify ripple effects
For the Hawaii Quality of Life system maps, certain elements are tagged with "leverage point". By using :from(.leverage-point), we can go from this:
to this:
Decorating connections based on properties of connected elements
Since this just extends the flexibility and power of selectors, you can also use :from( ) and :to( ) in the decorations you build with the advanced editor. You may want all connections coming from organizations to be a different color, or make sure connections coming out of an element tagged with "leverage point" are thicker.
That should get you started! Send us a note if you get stuck or run across any bugs with these selectors.
