D3 not installing with bower

[JordanCollins]

Just an issue that I found running through your tutorials: the d3 folder was not installed as part of my bower_components. Each of the other components were successfully installed, except for d3.

Ran into the same issue. The bower.json is missing a D3 entry. Fix:

"dependencies": {    
   "d3": "^4.11.0"                                                          
   ...

Alternatively, you can also install it with npm. Add the D3 line to package.json:

"devDependencies": {                                                          
    "d3": "~4.11.0",                                                            
    ....                        

You need to change the d3 path if you use npm to install d3.

I't won't work with 4.11.0 because of d3 x3 API changes. So it can be fixed with older d3 version.
Changes in bower.json:
"devDependencies": { "d3": "^3.5.17", ....
