D3.js line.curve() method
The d3.line.curve() method is used to give a curve to our line. D3.js provides several curve factories that can be used to give different curves.
Syntax:
d3.line.curve(curve_factory);
Parameters:
- curve_factory: type of curve to be given to the line.
Return Value: This method has no return value.
Example 1: In this example, we will use the curveBasis curve factory.
