Las categorías se ubican en el eje de categorías.

Empezar en 0 evita distorsiones visuales.

f_i indica cuántas ocurrencias de la categoría.

α se calcula con fi/N × 360°.

La amplitud se obtiene con fi/N multiplicado por 360°.

Porcentaje = fi/N × 100.

Barras permiten comparar valores exactos entre muchas categorías.

Circulares destacan participación relativa en el total.

Falta de etiquetas en ejes dificulta interpretación.

La suma debe ser 100% para representar el total.
