Bajo mi experiencia hay que tener 2 consideraciones claves como analistas de datos. Diseño de Visualizaciones Claras y Efectivas: No todas las visualizaciones sirven para todo tipo de datos o preguntas. Como recomendación siempre es armar un informe o dashboard en base a una plantilla de objetivos y palancas para ver qué gráficos son relevantes para el usuario. 1. ¿Cuál es el objetivo principal? 2. ¿Que palancas o indicadores impactan directamente en este objetivo? 3. ¿Qué tipo de usuario va a visualizar la información y con qué frecuencia? Arma tu maqueta previa y luego diseña para pedir feedback. La idea final es poder contar una historia con tus datos y que tu análisis tenga un impacto real en el negocio.
