The same data, drawn honestly and drawn to deceive.

A chart is a claim. This instrument renders one real series two ways, measures the gap between what the chart shows and what the data says, and grades it on Tufte's Lie Factor, the first continuous score for how much a chart lies.

Measure, then claim

The chart's visual effect matches the data.

Every value is computed live from the source table, exactly as the training labels are. Nothing here is judged by eye.
