This site—Actually Represented—is to demonstrate a version of self-districting. Instead of politicians and voting rights activists fighting over where to draw district lines, let the voters decide their districts.
The tabulation system uses "ranked approvals," a similar process to the method of equal shares. The main differences are instead of everyone getting a piece of a fixed budget, they each get one ballot (or vote) and parties can win more than once.
With this system, whatever party has the most points per round wins a seat provided they meet the minimum number of points needed. As with all self-districting methods, any district without enough party members to fill it will be a general (party-unaffiliated) district.
