The first chart clearly shows the recommended nutrient intake volumes. Amounts of nutrients intake decrease from the lowest part of the pyramid so that the highest part contains the nutrients that less important (MGMg, 2014). From the images, it easy to deduce the food nutrients represented in every category of the pyramid. The pyramid clearly indicates which food types should be consumed in large proportions as well as those that should be consumed in small amounts. In addition, the message on the pyramid matches the information provided along with the images. The color and design used on the pyramid is appropriate since it enhances clarity. From the chart the harmony of colors, which is a significant feature in visual communication, is clearly visible (Thalassinos, 2009) In addition to clarity of images, there are no signs of chart junk or alteration on the data.
The second chart represents a comparison of the mortality rate caused by malaria in the Sub-Saharan Africa and the world. Difference in color and the key makes the message on the chart clear.

In addition, there is numerous use of chart junk which makes the chart congested. On the chart, two different forms of visuals are used. There is considerable alteration on the data, which would mislead a viewer.
The message on the fourth chart deviates from the assumption given in the chart title. According to the title of the chart, minority communities experience low employment rates even in good economic times. However, the line graph depicts the minorities as the communities with high employment rates. The difference between the title and the data representation makes the message unclear (MGMg, 2014). With correct representation of the data, the chart would have been appropriate. In addition, the colors used to represent black, Hispanic and white communities to not bring out the actual meaning of the words. Alternatively, a lighter color could have been used to represent the whites and a darker one for the black communities. Apart from the contradictory information, there is much use chart junk which affects the clarity of the visual.
On the fifth chart there is information on the use broadband services at work and at home. The visual message is unclear owing to the use of unnecessary visuals. The grey color makes it difficult for a viewer to identify the section that represents rate at which people access broad band at work and at home. With the exclusion of the chart junk, the representation is highly suitable for the data. Different scales are used on the two charts. This may confuse the viewer when he/she is making comparisons.
The sixth visual represents two charts; one on environmental risk factors and the other on energy consumption by fuel. Information on the two charts is clearly represented through the use of different colors for the various types of fuel. The use of gas emission chimney models to represent the rate at which gas emissions increase makes the chart appropriate. In addition, alterations on the data aid in increasing clarity.
The last chart is a representation of the burden of disease caused by overconsumption of alcohol. Different colors are used to mark areas on the world map where alcohol related diseases are prevalent. Much clarity has been achieved through the chart since it does not require high inferential analysis. The chart is suitable for the representation of the data. Using another form of chart for range data would make the interpretation difficult. In addition the use of distinct colors on the chart makes it easy for the viewer to extract information from the chart.
