How to remove blank space around SVG

I made this codepen that might help others who don't want to deal with drawing tools:

https://codepen.io/Steve6886/pen/abzzdOG

EDIT: Here’s a more up-to-date version of my previous codepen solution: https://svgcrop.com

// USER: Set either a width OR height (will scale evenly)
const WIDTH = 100;
const HEIGHT = null;

// Grab the SVG and remove any existing viewBox
const svg = document.querySelector('svg');
svg.removeAttribute('viewBox');

// Set default coordinates
const coords = {
  top: Infinity,
  left: Infinity,
  bottom: -Infinity,
  right: -Infinity
}; 

// Filter SVG to visible elements
filterize = newSvg => {
  const newest = [...newSvg.children].filter(x => x.tagName !== 'defs' && x.tagName !== 'style' && x.tagName !== 'title' && x.tagName !== 'desc');
  if ((newest.length === 1 && newest.childElementCount > 0) || newest[0].tagName === 'g') {
    return filterize(newest[0]);  
  }  

  return newest.filter(x => (x.getBoundingClientRect().top !== 0 && x.getBoundingClientRect().left !== 0 && x.getBoundingClientRect().bottom !== 0 && x.getBoundingClientRect().right !== 0));
  
} 

// Get coordinates of SVG elements
filterize(svg).forEach(x => {
  const {top, left, bottom, right} = x.getBoundingClientRect();
  if (top < coords.top) {
    coords.top = x.getBoundingClientRect().top;
  }
  if (left < coords.left) {
    coords.left = x.getBoundingClientRect().left;
  }
  if (right > coords.right) {
    coords.right = x.getBoundingClientRect().right;
  }
  if (bottom > coords.bottom) {
    coords.bottom = x.getBoundingClientRect().bottom;
  }
}); 

// Set viewBox based on coordinates
svg.setAttribute('viewBox', `${coords.left.toFixed(2)} ${coords.top.toFixed(2)} ${(coords.right - coords.left).toFixed(2)} ${(coords.bottom - coords.top).toFixed(2)}`);

// Set given width OR height
WIDTH && svg.setAttribute('width', WIDTH);
HEIGHT && svg.setAttribute('height', HEIGHT);  

// Add textarea with new SVG code to copy
const textarea = document.createElement('textarea');
textarea.style = `display:block;margin-top:2rem;width:100%;padding:0;min-height:calc(100vh - ${getComputedStyle(svg).height} - 2rem);`;
textarea.innerHTML = svg.outerHTML;
document.body.appendChild(textarea); 

I opened your svg on Inkscape and resized the document size to fit the content. (File -> Document Properties -> Resize page to content -> Resize page to drawing or selection)

Output:

Now that the svg was fixed, you can put it in your file and set the height. In this case height:70vh; (For performance reasons, it's recommended to set height and width, but it's up to you).

#Layer_1{ /*Change svg id to a meaningful name*/
    height:70vh
}
