1. In a data visualization computing system, a computer implemented method of determining transition boundaries from data values in a data set for the generation of a graphical heatmap representation of the data values, the method including the steps of the data visualization computing system:

  • retrieving the data values in the data set;

    determining a logarithmic base value, wherein the base value is calculated based on the retrieved data values; and

    generating transition boundaries for the heatmap representation by calculating transition boundary values, wherein the transition boundary values are calculated using an exponential function with a base value equal to the determined logarithmic base value and an exponent value that is incrementally increased from a value of one to a maximum exponent value to represent the retrieved data values.
