I have this code : 

```css
#circleSVG {
 fill : red;
}
```

```html
<svg>
  <g transform='translate(100,100)'>
    <circle id='#circleSVG' r='5'></circle>
  </g>
</svg>
```

JSFiddle : <https://jsfiddle.net/thatOneGuy/x2pxx92e/>

Is it possible to style the circle via CSS ? And not inline like so (I am using D3) : 

```
d3.select('#circleSVG').style('fill','red');

```
