Un enfoque a tener en cuenta a la hora de crear una visualización de datos es definir claramente si el output procede de un análisis univariante o un análisis multivariante. El análisis univariante se enfoca en una única variable. El principal objetivo es describir y resumir la distribución de la variable que se quiera explicar. Con ello podemos tener un mayor entendimiento del universo con el que estamos trabajando. Imagínate que tenemos una variable que mide la edad en años ¿la población de nuestro dataset es joven? El análisis multivariante examina variables simultáneamente para identificar relaciones lineales entre ellas. Con ello podremos encontrar patrones que nos permitan obtener un entendimiento más profundo del dataset.
