Dear Shadow Chancellor,
An important role of data visualisation is to aid understanding of the data. But in this case the graph is misleading as neither the piles of coins nor the flags display the growth forecasts to scale, as shown in the annotated version in this letter. That said, it remains the case though that the UK was the only country for which negative growth was forecast.
Officials from the UK Statistics Authority have spoken to your office on this subject.
Sir Robert Chote
Chair of the UK Statistics Authority
