    Hi,
    You really do not need to use Python for the plotting to be honest.  I have attached a process below which generates two columns and clusters the data.  At the end, you can simply click on Visualizations and set up the chart as desired (see below):


    The process is below.
    Hope this helps,
    Ingo

    thank you so much 
    but i want to make 3 dimensional visualization, can i do it without using python code

    Yes, that is possible as well.  You simply select "Scatter 3D" as the plot type.
