title: plotly visualisation is too slow for United states county map
body: <p>My data set has about 90K rows with follwing columns</p>
  
  <pre><code>state_name, county_name, county_lat, count_long, value_x
  </code></pre>
  
  <p>A similar direct example just for California counties <a href="https://plot.ly/r/county-level-choropleth/" rel="nofollow noreferrer">here</a></p>
  
  <p>Although it works fine for one sate, when I do for all the states in US, the plot is slow when i try to zoom in and out and also hovering data takes time to load. The plot generation itself takes a bit of time</p>
  
  <p>Is there any solution to overcome this lag? If not, are there interactive plots like <code>plotly</code> that has hover and zoom features and visually colourful to plot maps?</p>
