I don't find the possibility of distraction to be more important than the possibility of deception. If you conceal data because it is distracting, the person from whom you are hiding it cannot know why you did that. They only know that they cannot see what you refused to show. If it is not relevant, it is better to show it, and explain why it is not relevant as best as you are able. And that explanation can take the form of an arrow that marks the earliest time life was suspected to have first developed. But in showing it, an observer might be able to discern temperature trends due to changes in the sun, meteor and comet bombardments, loss of core radionuclides, radiation into space, or other cosmological factors not attributable to humanity, or other forms of life. It might show a reason why the Earth today should be cooler now than it was at the Eocene maximum. It's just more honest. You can still show a second graphic that cuts out the pieces you feel to be unimportant, and which highlights the pieces that best make your point.
