The Pictograph

A one-page pictograph — the isotype or unit chart your school textbooks used — that turns each amount into a row of little squares, every square worth the same fixed quantity, so a bigger number is simply more squares. It trades the length of a bar, which your eye has to measure against an axis, for a count, which you read the way you read a tally: ten squares beats six, and you never had to glance at a scale to know it. That makes it friendlier than a bar chart for anyone skimming the page, and it is the classic way to make a statistic land — one square per thousand people, per hour, per dollar — because the quantity sits right there to be counted. One shared "each square equals" scale runs across every row, picked automatically as a round number so your biggest row fits neatly, or set by hand when you want a specific unit; the last square in a row part-fills to show the leftover. Each row keeps its exact value on the right and the header totals them up. It works best for a handful of categories you want to compare at a glance — hours by activity, sales by product, servings by food group, spending by category, headcount by team. List a label and an amount per line and the squares, scale and part-fills all place themselves; leave it blank to print an empty grid and shade the squares in by hand.
