Progress To Goal (Radial Bar Charts) — Plot.Ly

# SISENSE FOR CLOUD DATA TEAMS PROGRESS TO GOAL TEMPLATE
# SQL output should have 2 columns:
#    1) current: the currently attained value
#    2) goal: the goal value
#      optionally apply dollar formatting by naming the columns current_$ and goal_$
