I'm sorry, as a text-based AI language model, I cannot generate a visual representation of a bar chart. However, I can suggest that one way to represent the given data in a bar chart would be to use the values as the heights of the bars, label the x-axis with the meaning of the values, and label the y-axis with their specific values.
