Multi-series line chart with tooltip

Chinooks are responsible for large temperature variations in southern Alberta, Canada. The interactive multi-series line chart shows temperatures measured in two Calgary locations — Springbank and Calgary International airports — on 22 November 2017. Hovering over the visualization causes a tooltip containing temperatures in the said locations to be displayed.

This visualization was implemented with D3.js version 4.12.2 and based on Mike Bostock's Multi-series Line Chart and X-Value Mouseover blocks.
