Line Chart using React.js d3.js & TypeScript with the help of d3.bisector interaction — Part I

To create interactivity of the mouse following the plotted data there is a need to do a calculation of the closest point to the mouse. Luckily, d3 has a method d3.bisector that can help us with these calculations. In this two-part tutorial, I will show you how to work with d3.bisector.

In this first part, part one, I will be working with two linear scale values as the metric and in part two I will be working with value and time metrics using d3.bisector.
