Convert geopandas shapely polygon to geojson : <p>I created a circle using geopandas and it returned a shapely polygon: </p>

<pre><code>POLYGON: ((...))
</code></pre>

<p>I want this same polygon as a geojson object. I ran across this:</p>

<pre><code>shapely.geometry.mapping(shapelyObject)
</code></pre>

<p>which returns this:</p>

<pre><code>{'type': 'Polygon', 'coordinates': (((570909.9247264927, 125477.71811034005)...}
</code></pre>

<p>But when I try to map this in mapbox it does not show anything. I think maybe it is not fully a geojson object.</p>
