Had to explictly install d3

[apoorv-kumar]

For some reason npm install didn't automatically install d3 and I was getting the following error -

ERROR in ./ ~ /react-vis/dist/plot/axis/decorative-axis.js
Module not found: Error: Cannot resolve module 'd3-format' in ${WORKING_DIR}/story-generator/node_modules/react-vis/dist/plot/axis
@ ./ ~ /react-vis/dist/plot/axis/decorative-axis.js 15:16-36

ERROR in ./ ~ /react-vis/dist/radar-chart/index.js
Module not found: Error: Cannot resolve module 'd3-format' in ${WORKING_DIR}/story-generator/node_modules/react-vis/dist/radar-chart
@ ./ ~ /react-vis/dist/radar-chart/index.js 39:16-36

I did npm install d3 and then npm start -s works.

@apoorv-kumar d3 isnt added as dependency in the package.json.

[apoorv-kumar]

@tejasrivastav It should be added right ? The project doesn't seem to work otherwise.

@tejasrivastav @apoorv-kumar True, D3 isnt added as dependency in the package.json but has been added explicitly to support topojson to convert topojson data to geojson. I was having issues in installation and importing of the modules, so I included in explicitly. There arn't any other dependency for d3. The visualization are built using react-vis and vanilla js. React-vis uses d3 built for that it doesn't need to be included additionally.

@akshay2905 d3 isnt added as dep in react-viz repo correct if im referring to same

[imakshayverma]

@tejasrivastav it is actually. It is based on React and d3. Sharing the package.json file for react-vis - Link

They have included invidual components of the d3 library to serve different purposes

[apoorv-kumar]

@akshay2905 I see. It might be useful to include this additional step in the installation documentation. I'm new to the scene so it wasn't obvious to me. Happy to raise a PR for it.

@apoorv-kumar We might need to probably diagnose the issue here. As it is not a reported as common issue by others. Managing packages with npm can be a little tricky at times. There might be other issue at play. At what stage did you face this problem?

[apoorv-kumar]

During my first npm start -s, I got the error I shared above. It might be that typically people have d3 installed in the global npm libs and I didn't.

@apoorv-kumar Possible. Will check with a few others if the same problem exist.
