1. An Overlap toggle option is available in Data Labels settings to control the visibility of overlapping data labels on charts.

2. The visibility of data labels depends on factors such as available chart space, font size, number of data points, and label placement. In scenarios with limited space, some labels may be automatically hidden to avoid overlap and maintain chart readability.
   
3. Enabling the Overlap option allows data labels to be displayed for all data points, even when labels overlap on the chart.
   

1. Data labels are displayed for all data points on the chart.
   
2. Labels that are normally hidden due to insufficient space or overlap conditions are rendered.
   
3. Overlapping labels are allowed to appear on the chart regardless of chart density or font size settings.
   

1. Ensures visibility of all data point values.
   
2. Useful for charts containing dense datasets or multiple data points.
   
3. Helps users analyze all available values without automatic label suppression.
   

1. Overlapping labels may reduce chart readability in highly dense visualizations.
   
2. It is recommended to use appropriate chart dimensions and font sizes for improved visibility.
   
3. This option is applicable wherever data labels are supported in charts.
