Why is it not advisable to connect the data points for each organism in your graph?

Connecting the data points for each organism in a graph can misrepresent the nature of the relationships between the data points. Unlike continuous data, many biological data sets are discrete or categorical, making it inappropriate to imply a direct connection or trend between each organism. This can lead to misleading interpretations, as it suggests a level of continuity or correlation that may not exist. Instead, using distinct markers for each organism allows for clearer visualization of their individual data without implying false relationships.
