  "alt": "Lines by cycle of first gift. The share near the center is highest for the earliest groups and falls toward zero for groups starting after 2012, under three recipient filters. A second view compares first-time and repeat donors by cycle, with repeat donors above first-time donors from 1990 on and both falling. A third view shows the share of each cycle's pool by decade of first gift, with the pool made up of newer groups over time.",
  "caption": "Groups that first gave from 1990 on are less often near the center than the groups of 1980 to 1988, with exceptions between neighboring groups. DIME gives every donor one score, so a group's share does not change after it arrives; the pool's share falls as newer groups replace older ones. The first view counts donors and the second counts donors active in each cycle.",
