A misleading bar chart

A client wants a bar chart where the y-axis starts at 95 so a rise from 96% to 98% looks huge. What should you do?

A.Do it; it is the client's dataB.Explain that bar charts should start at zero because bar length encodes value; suggest showing the change honestly, for example with a clear label or a dot or line chart with a labelled scaleC.Remove the axis labels so nobody noticesD.Use a 3D chart to make it look bigger
