In consulting firms such as McKinsey, there are very strict rules about formating slides. Data labels for example are always placed outside the horizontal bar. The chart below (ripped out of its context from this NYT article) uses a different approach:
The data labels are placed next to the horizontal bars where you would expect the axis labels to be. I am fine with this approach. The relative size of the bars gives a global view of the order of magnitude of the values, and for whomever is interested the data labels provide the exact values.
