While the quadratic bezier curve (Q) is great when we want to bend a line, often its not flexible enough. With the outer group we translate the whole star downwards by 5 units.

Now that you've got a glimpse about the format, you might already have an idea how the post's topic is to be solved - by means of DOM - manipulation. We append the base circles to the baseGroup, which is clipped by the clipPath group. You can see the SVG attributes were added correctly and the size was set for us. Circles? Here we have a series of quadratic Bziers curves (Q) where the control points get further and further away from the center of the tree as the path goes down. The overlay applies the 'multiply' blend mode in order to darken the entire image. Within, there's one (or several) tags that describes the shape of the SVG.

The base circles with color are created the same way as the last demo so I wont cover that again. These posts are fetched from jsonplaceholder and dynamically added to the DOM by a function inside the. We accomplish this by creating thousands of videos, articles, and interactive coding lessons - all freely available to the public. It can be used to make graphics and animations like in HTML canvas. @user104317 I want to do this in Javascript because the use case is in a angular directive creation. Add the following inside the main.js file, right after placing the text-content: // TODO: Add the icon function here renderLinkIcon(postTitleAnchor); And that's it.
