Security is a very prominent concern for residents of the northern suburbs of Johannesburg and something that is on people's minds a lot of the time. Because security is such a major issue it is of interest to people to get a bigger picture of the security measures that they take to make them feel safer so that they can see the bigger picture when it comes to security. This would also help people in improving or changing their security measures depending on the areas that they live in.

This project is design for people who are unfamiliar with living in Johannesburg so that they can see the number of people that use each type of security measure to feel safe in Johannesburg as a whole and within each suburb. This data visualisation allows the user to arrange the data in a number of different ways and make a number of different comparisons. People can also look at individual instances and see what combination of security measures they use and what they find most effective. Each questionnaire is represented on the graph in order of the time that they answered and the user can click on each answer and the user can see the exact time in which they answered. By including a time element to the Data Visualisation one is able to see security measures that become most important in people’s lives at specific times of the year. This is important because crime can increase at certain times of the year. 

At the moment the data is mostly from people in the northern suburbs of Johannesburg which means it is quite a biased view on security in Johannesburg as a whole. However it still has the potential to be expanded into more areas of Johannesburg to get a broader view of Johannesburg security. 

There are a lot of misconceptions about security that are also revealed through this data visualisation for example vigilance is mentioned as a safety measure a lot more than blocking mechanisms such as high walls or electric fences. it also might inform people about different security measure that they may not have thought of and that they might find more useful then current security measures. At the moment the data is largely based on physical circumstances but I was hoping to also focus on psychological means of feeling safe and expose what security measures are necessary for physical security and which measures people use for psychological reasons. 

This makes the graph more than just about physical safety but about the psychological and social aspects of feeling safe. The data visualization is based on open ended questions which makes the outcome of the data visualization have a lot more in-depth feedback and a lot more information for the user to explore. The data is structured in a way that is simple and clear for a good user experience and gives instructions to guide the user in achieving their desired goals.
