Data visualization is one of the forms that provides accessibility of data. The data visualization pictures chosen include; Your Olympic athletic body matches, non-UK born census data, and better lie index. The data provided in the visualization deliver real examples reflecting actual case studies as they manipulate the raw data to an actual presentation (Sarkar, 2016). For instance, the visualization of the Olympic Athletic Body match provides a correlation between the body weight and height of the athlete.

The data presented on the graph indicates the presence of a strong correlation between the two variable- weight and height. The data in the visualization presence a raising plane moving from left to right. Plotting a curve could predict the best line of fit that could be used to analyze the data and draw conclusions.

Sarkar, (2016) argues that the best way to improve the data is to provide, in the visualization, the best line of fit and statistical explanations regarding the data presented. For example, the visualization on the Non-Uk born census, there is no any statistical explanation to make the reader understand what is going on in the visualization. Having analysis statistically on the paper provides an easier element of understanding to the view.

Data presentation provides a different platform for the data assessment in the form of data visualization. Better life index, Shakira: the click don’t lie are some of the visualizations that got my attention in the field of data visualization (Helfman, & Goldberg, 2014). These are the kind of visualization that provides essential information to the viewer with just a glimpse.

The visualizations were effectively communicating and made a clear presentation even from their topics. Shakira: the click doesn't lie presents the number of followers, and likes that Shakira has on her social media platforms. The figures talk for themselves as the celebrity is a popular individual in the public domain. The figures, however,have a clear indication of what they represent in the real world other than a symbol of popularity and fame (Helfman, and Goldberg, 2014)

Improving visualization would mean representing the data in a simplified form and them plotting them in the form of graph could improve the visualization making it presentable and understandable as possible.
