This sample visualizes Gartner's data on global PC shipments in 2020, broken down by quarter and brand (Lenovo, HP, Dell, Apple, Acer, ASUS, and Others). Custom labels convert raw values to millions, point padding separates tiles, a union HTML tooltip shows all brand figures per quarter, and an HTML title headlines the chart.
