The visualization above illustrate  the risk of different groups of people experience crash death. I trust this dataset because this data was provided by the Department of Transport. It covers the years 1999 to 2008, the last year for when complete data is available. Drawn from the official statistics, the data is gathered by the police at the scene of every serious road crash. There are also limitations for this data, for instance, the place of accident happen, the names, birth places of victims are not investigated. With this kind of limitations, we can not get a overall understanding about where is the most easily get car crash place either will not do any improvement correspondingly. In my point of view, as the visualization above is edited by BBC journalist, they try to easy the way getting access to various crash explanations which provided several buttons on the left for people to select the areas they really interested. Similarly, the exact numbers of victims will shown to all as soon as the reader clicks on the different colors.
