In this paper, we focus on the specific design space of temporal data visualizations. Whereas most visualizations do not take into account the special semantic of temporal data, we depict ecological representations of the time that may be reuse by practitioners and we explain why their specific semantic helps users perceiving information. Furthermore, ecological designs create emerging data. Thanks to our characterization model, we show how to analyze such visualization and how to assess its efficiency in term of a number of the emerging information. This model and this assessment help designer to understand their design space, to compare designs.
