Description
It would be useful if Plotly exposed functions to map floats, e.g. values in [0,1], to corresponding RGB strings formatted as 'rgb(255, 0, 0)'. There are lots of use cases for this. For example, if you want to plot a network where each edge is colored according to a weight between 0 and 1 using a continuous color scale. The only way I know to do this right now is to make a separate trace for each edge in the graph and specify its color manually.
