The color gradient from 'hot' (darker) to 'cold' (lighter) visually represents the range of values. 'Hot' colors signify higher values or counts, while 'cold' colors indicate lower numbers. This gradient helps in quickly identifying significant figures in the data.

Data within tables is primarily sorted by count, followed by the total amount raised. This sorting approach emphasizes the most active or successful fundraising types, providing a clearer insight into our fundraising efforts.
