The graph shows a crossover interaction, where the lines representing the two different levels of one factor (indicated by the different colors) cross over each other. This indicates that the effect of one factor depends on the level of the other factor. There is no evidence of main effects, as the lines are not consistently higher or lower for one level of a factor compared to the other. Therefore, there is an interaction effect but no main effects.
