title: plotting polygons in python using geopandas
body: <p>I have a data frame with latitude, longitude and annual consumption data. I am trying to plot the annual consumption data using GeoPandas with a quantile scheme by making a polygon column. I followed the following tutorial.
  <a href="https://geopandas.org/en/stable/gallery/choropleths.html" rel="nofollow noreferrer">enter link description here</a></p>
  <p>I used the latitude and longitude data to make polygon shapes using the following code.</p>
  <pre><code>full_dataframe[&quot;geometry&quot;] = Polygon(list(zip(full_dataframe[&quot;long&quot;], full_dataframe[&quot;lat&quot;])))
  
  merged2 = GeoDataFrame(full_dataframe)
  
  merged2.plot(column='annual_consume', scheme='quantiles', k=4, edgecolor='k', 
               cmap='OrRd', legend=True,
               legend_kwds={'loc': 'center left', 'bbox_to_anchor':(1,0.5)})
  
  </code></pre>
  <p>My data frame looks like below

  <p>The issue is, when I plot it, it looks like a big mess of interconnecting points. The boundaries are not seperated.</p>

  <p>I want a similar boundary separation like the tutorial based on longitude and latitude data.</p>
