Discussion

A. Note how enormously misleading the red and blue bars are. There is absolutely no reason for their presence in this graph. Even if they were actually scaled to the number of total new jobs, a two-axis graph would still be difficult for most people to understand. The figure also doesn’t take into account a host of potentially confounding factors, including (but not limited to) population growth, women entering the workforce, shifts from part-time to full-time jobs, change in wages and GDP change.

B. The design of the food pyramid changed recently, in part because the visual characteristics of the old pyramid did not correspond well to the numerical recommendations. The new designer makes the same mistake but disdains “misleading” in favor of “mindbogglingly dishonest.

C. The flashy background and bright colors must have distracted this graph’s creator from the fact that it’s useless. Think the graph is describing crime rates? Think again. It actually describes the percentage change in violent crime rate.

D. The point of a pie chart is presumably to facilitate a comparison of land use, but this pie chart makes that very difficult. Given the combination of the huge number of categories and the huge change in their values, this would have been better rendered as a table.

E. This graph is a painful experience all around. Income is described as “percentile” but is shown in ranges. The category labels are placed randomly around the data points, rather than at the bottom where they belong. The data points are tremendous circular blobs that are impossible to compare at a glance.

F. Two-axis charts are as bad as any idea, especially when it’s not clear what the two variables actually are. But the worst part? It isn’t population adjusted. The states with the most deaths are the states with the most residents: California, Texas, New York and Florida.

G. The data in the table is presented more effectively, it’s too sparse to be of much use: how do those raw figures compare to tax rates, GDP, individual wealth or the many other factors that prevent easy comparison of states?

H. The several subtle flaws could mislead the casual observer. To the lower right, we see three blocks labeled “7%” that have wildly different heights, presumably because of rounding in display. Dropping the decimal points is sometimes acceptable, but you can’t have it both ways: either those digits matter and should be shown, or they don’t matter and shouldn’t appear anywhere in the graph.

I. This map purports to show the number of murdered transgendered people over a one-year period. But there’s a big problem: there is no data for the vast majority of the world.

Recommendations

A. There should be good use of infographics to represent information.

B. There should be correct corresponding of data in the pyramid and in the description.

C. There should be use of dull background colors .

D. The pie chart shouldn’t be used for comparison of the data. Tables would be better to represent the information.

E. The income should be presented in terms of ranges.

F. Two axis charts are more confusing for very different information presented.

G. The information is too sparse for the map.It should be more detailed.

H. There should be good use of data representation.

I. The map should be well designed and labelled.

Charts and graphs have found their way into news, presentations, and comics, with users from art to design to statistics. The design principles for these data graphics will vary depending on what you’re using it for. Making something for a presentation, One should keep it extremely simple and avoid using a lot of text.
