   “If we just plopped down a dot for every observation we’d end up with an undifferentiated black blob, so the weathergami technique visualizes frequency of temperature pairs: we divide the chart area into a fine hexagonal grid, and then color each hexagon according to how many daily observations fall within it.”

2. Having three equal axes which cross at 60° angles, and an unequal axis which crosses the others at 90° angle.
