Angular - deploy your app in a sub folder

 

If you want to deploy your app in a sub folder you need to add the build flag --base-href

Example

C:\Users\xxxx\Documents\works\ng\my-app>ng build --prod --base-href=/dist/my-app/

D3 tooltips - show tooltip in a different location

Sometimes you need to manually specify a target to act on. For instance, maybe you want the tooltip to appear over a different element than the one that triggered a mouseover event. You can specify an explicit target by passing an SVGElement as the last argument.

tip.show(data, target)

Check working example here 

The API for the above code is found here under Explicit targets
