subject = ['Moe','Larry','Curly','Moe','Larry','Curly','Moe','Larry','Curly','Moe','Larry','Curly']
score = [1,6,2,8,2,9,4,5,1,5,2,8]

data = [dict(
  type = 'scatter',
  x = subject,
  y = score,
  mode = 'markers',
  transforms = [dict(
    type = 'groupby',
    groups = subject,
    styles = [
        dict(target = 'Moe', value = dict(marker = dict(color = 'blue'))),
        dict(target = 'Larry', value = dict(marker = dict(color = 'red'))),
        dict(target = 'Curly', value = dict(marker = dict(color = 'black')))
    ]
  )]
)]

fig_dict = dict(data=data)
pio.show(fig_dict, validate=False)
