Bad Visualizations


The intention of this graph is representing if people are willing to pay more for their milk to help dairy farmers. The pie chart is actually the most proper choice to help visualize proportions of each choice out of total sample, but this pie chart is surly misguiding.  Since for this question, there are only two answers, either yes or no, the pie chart is divided into two pieces. However, the proportion of each option takes on the chart can not accurately does not match the actual  percentage.   There are 87% people answers “yes”, which means the majority of the chart should be white correspondingly, but this graph both of them take 50% of the space,which is a mismatch with the actual data.


This visualization is supposed to represent the increment of smart phone user annually. There are three pie chart which are supposed to indicate percentage of smart phone user over total cell phone user at year 2009, 2012, 2013. Although it looks straightforward at the first glance, the pie chart


Bad Data Visualizations

In everyday media such as magazines and newspapers, we are constantly bombarded with attractive graphics that attempt to catch our attention while displaying useful data and statistics. Unfortunately, even the best looking graphics can have major flaws. Below, we’ll explore some example graphics and try to find where they went wrong.

Bad Visualization Ex1


The intention of the map in the above graphic is to visualize the statistic, “29% Millennials (Born after 1980).” Firstly, it is difficult to understand what this statistic means. It could use some additional context or explanation. Moving to the map of the image, the bottom of the bottom of the map is filled in proportionally to statistic, but there is no reason to use a US map since the location where the map is filled in does not relate to the statistic at all. This map misleads people into thinking the that millennials live in the south, and therefore poorly implements the usage of self-representing images.


Bad Visualization Ex2


At first glance, this chart is confusing because the percentages do not appear to match the relative sizes of the chart segments. For example, when seeing a percentage such as 93%, you would expect its corresponding segment to fill 93% of the chart. This graphic could have been better implemented using a different type of visualization for the statistics. Additionally, the graphic should have provided additional data or further explanation to help the viewer understand the importance of social media marketing, as was expected from the title.

Bad Visualizations


The pink color and the usage of cosmetics make the visualization look attractive. However, the sizes of these cosmetics do not show the relevance among the data; and the percentages are not well arranged. The percentages of IND, JPN and CHN are different, but the cosmetics which represent them are exactly the same. the 17.9%(USA) is just a little bit taller than 4.9%(MEX). The country flags seem to be irrelevant because there are already country labels under the cosmetics.



This visualization uses two rings to indicate one comparison, which confuses me. the blue and grey color seem irrelevant to the data, but actually represents the percentages. It will be better if there is only one pie chart labeled the texts and percentages.
