Line graphs are the most popular graph type you see used on websites; often created to plot one or more datasets over a period of time. Think polling for elections, weather charts, health monitoring, sales figures, trending products or services, financial markets and other statistical analysis. The aptly-named LineGraph stack is a single stack that specialises in just doing line graphs only, to go on websites. It has some pretty powerful features, but remains easy to setup and is fully mobile responsive.
