visualisation data error

[Rmfjd1978]

I'm using the visualization control and is giving me the following error: TypeError: Object of type Data is not JSON serializable

plotdata = data('year person sales', 10, rows=[
        ('2021', 'Joe', 10),
        ('2022', 'Jane', 58),
        ('2023', 'Ann', 114),
        ('2021', 'Tim', 31),
        ('2023', 'Joe', 96),
        ('2021', 'Jane', 55),
        ('2023', 'Jane', 5),
        ('2022', 'Tim', 85),
        ('2023', 'Tim', 132),
        ('2022', 'Joe', 54),
        ('2021', 'Ann', 78),
        ('2022', 'Ann', 18),
    ])
	

plotheatmap = ui.plot(marks=[ui.mark(type='polygon',
                                     x='=person',
                                     y='=year',
                                     olor='=sales',
                                     color_range='#fee8c8 #fdbb84 #e34a33')])	
									 
ui.visualization(plot=plotheatmap,
                 data=plotdata)

pack=True parameter is needed for your data:

plotdata = data('year person sales', 10, rows=[
    ('2021', 'Joe', 10),
    ('2022', 'Jane', 58),
    ('2023', 'Ann', 114),
    ('2021', 'Tim', 31),
    ('2023', 'Joe', 96),
    ('2021', 'Jane', 55),
    ('2023', 'Jane', 5),
    ('2022', 'Tim', 85),
    ('2023', 'Tim', 132),
    ('2022', 'Joe', 54),
    ('2021', 'Ann', 78),
    ('2022', 'Ann', 18),
], pack=True)
