careful not to fall into a conceptual trap by adop>ng accuracy as a criterion. We are not saying that the primary purpose of a graph is to convey numbers with as many decimal places as possible. … If this were the only goal, tables would be beaer. The power of a graph is its ability to enable one to … see paaerns and structure not readily revealed by other means. -‐ Cleavland and McGill (1984)
be careful not to fall into a conceptual trap by adop>ng accuracy as a criterion. I am not saying that the primary purpose of an animated map is to convey data with as much accuracy as possible. … If this were the only goal, sta5c maps would be beaer. The power of an anima5on is its ability to enable one to … see spa5al-‐temporal paaerns and structure not readily revealed by other means. -‐ Merson (today!)
-‐ “Mo5cons”/semi-‐sta5c Dynamic Data -‐ Linear flow data (water) -‐ Surface flow (pollu5on, wind) -‐ Moving points (migra5on, airplanes) Snapshots of intrinsically, con0nuously moving data represented with mo0on What is being shown How is it shown
accuracy assessments • how quickly and correctly users can complete specific, usually low-‐level, tasks eye-‐tracking • gaze path paaerns • Top-‐down assessments (broadly in cartography) – less common for map assessments – memorability evalua5on assessments – learning facilita5on assessments – task outcome assessments Does the anima5on work?

1) have reduced speed and accuracy of responses to specific map data ques5ons. However, 2) report a more posi5ve and thought provoking experience 3) remember more informa5on with more accuracy, and remember a more posi5ve experience
