Chart_color not working in pie chart
only working in bar chart and line chart

For a pie chart you should provide an array of colors depending on the group_by_field option. In your case it's grouped by the name field the color array may be something like the following.

'chart_color' => ['Michael' => '255,0,0', 'George' => '0,255,0', 'Lisa' => '0,0,255']

If you group your data by the year of the created date of a model it depends on the group_by_period.

'group_by_field' => 'created_at',  
'group_by_period' => 'year',  
'chart_color' => ['2020' => '255,0,0', '2021' => '0,255,0', '2022' => '0,0,255', '2023' => '128,0,0', '2024' => '0,128,0']
