title: React Could not find a declaration file for module 'react-vis'
body: <p>I installed react-vis library for my react code.<br/>
  I used this command, like in the tutorial: <code>npm install react-vis --save</code><br/>
  But when I include the library with this code: <code>import {XYPlot, XAxis, YAxis, HorizontalGridLines, LineSeries} from 'react-vis';</code> <br/>
  It gives me the following error:<br/></p>
  
  <p><code>Could not find a declaration file for module 'react-vis'. 'C:/react-vis/dist/index.js' implicitly has an 'any' type.</code><br/><code>Try npm install @types/react-vis if it exists or add a new declaration (.d.ts) file containing declare module 'react-vis';</code><br/>
  And even that doesn't work.
  Anyone know how to do this?<br/>
  I'm just a beginner in react.</p>
