Not Assignable Error (update method)

[JojiKoike]

Thanks to your good angular with d3 sample program.
But, I've found error as below.

In multi-lne-chart.ts line 117,
.merge(charts)
Occurs an error as below

Argument of type 'Selection<BaseType, ChartPoint[], BaseType, {}>' is not assignable to parameter of type 'Selection<SVGPathElement, ChartPoint[], BaseType, {}>'.
Type 'BaseType' is not assignable to type 'SVGPathElement'.
Type 'Element' is not assignable to type 'SVGPathElement'.
Property 'pathSegList' is missing in type 'Element'. [2345]

I've implemented as below and worked correctly.
.merge(charts as Selection<SVGPathElement, ChartPoint[], BaseType, {}>);

Is this correct ?

My Environment is

• Angular : 7.0.0
• d3 : 5.7.0
• d3-interpolate-path : 2.0.1

Thanks and regards
