Heatmaps can show categorical as well as quantitative data. Categorical data is color coded. For example, a heat map can show bad, average, good in 3 different colors. Quantitative data is usually shown using a gradient scale of colors.
 

Can heatmap be used for categorical data?

It can be used to plot heatmaps on categorical variables or, otherwise, plot continuous variables with categorical color range.
