This is the graph showing valuation of Facebook, Inc. Though it is simple bar graph you can identify many problems in this visual.<\/p>\n

Normally we judge values of the bars in the bar graph by its length. Here the second bar appears to be twice as high as of the first bar. One can conclude that valuation is doubled from December to January. Every bar graph needs a zero on its scale.<\/p>\n Second, the horizontal axis is evenly spaced but dates are confusing the reader. There is one bar for December, one for January, none for February, two for March, and so on. Therefore, the trend that results from following the top of the bars is distorted.
