title: Vega editor "table is empty"
body: <p>I am trying to build an elementary plot showing proportion of energy source by continent. I've already cleaned up the data and uploaded a .csv file here : <a href="https://raw.githubusercontent.com/mkeutgen/dataviz_energy/main/prop_source_by_continent_2015" rel="nofollow noreferrer">https://raw.githubusercontent.com/mkeutgen/dataviz_energy/main/prop_source_by_continent_2015</a>
  Yet when I try to import it in vega lite editor, it states that my csv is empty.</p>
  <p>Here is the code I've written :</p>
  <pre><code>{
    &quot;data&quot;: {&quot;url&quot;: &quot;raw.githubusercontent.com/mkeutgen/dataviz_energy/main/prop_source_by_continent_2015&quot;},
    &quot;mark&quot;: &quot;bar&quot;,
    &quot;encoding&quot;: {
      &quot;x&quot;: {
        &quot;field&quot;: &quot;continent&quot;,
        &quot;type&quot;: &quot;nominal&quot;,
        &quot;domain&quot;:[&quot;Africa&quot;,&quot;Europe&quot;,&quot;Asia&quot;,&quot;North America&quot;,&quot;South America&quot;,&quot;Asia&quot;],
        &quot;title&quot;: &quot;Continent&quot;
      },
      &quot;y&quot;: {
        &quot;field&quot;:&quot;prop&quot;,
        &quot;aggregate&quot;:&quot;sum&quot;,
        &quot;type&quot;: &quot;quantitative&quot;,
          &quot;stack&quot;:  &quot;normalize&quot;
      },
      &quot;color&quot;: {
        &quot;field&quot;: &quot;share energy&quot;,
        &quot;type&quot;: &quot;nominal&quot;,
        &quot;scale&quot;: {
          &quot;domain&quot;: [&quot;coal_share_energy&quot;,&quot;gas_share_energy&quot;,&quot;nuclear_share_energy&quot;,                                       &quot;hydro_share_energy&quot;,&quot;renewables_share_energy&quot;,&quot;oil_share_energy&quot;],
          &quot;range&quot;: [&quot;#e7ba52&quot;, &quot;#c7c7c7&quot;, &quot;#aec7e8&quot;, &quot;#1f77b4&quot;, &quot;#9467bd&quot;]
        },
        &quot;title&quot;: &quot;Weather type&quot;
      }
    }
  }
