I am a huge sucker for simplistic and beautifully designed visual data on the web. Most data tends to be graphed via line or bar systems - which is fine - but I think slope graphs are highly underrated. Let's change that, shall we?

The HTML

For this concept we will actually be building this graph out of tables - crazy, right? The greatest benefit of rendering all the data inside of a table element is the ability to easily support smaller screens and mobile devices. Larger viewports will get to see the pretty slope graph, while those below a certain threshold will view a simple table.

(But more on that in the CSS section)

As you can see, nothing too fancy is happpening here. Pay close attention to the data-set and data-name variables though - those will be important for the CSS portion of this design, mainly the rendering of the line elements.

Now we need to design how our slope graph will look on larger screens / desktops. For this instance, we will target these larger devices with a min-width media query of 800px. The rest of the CSS might look a little confusing but I assure you it is quite simple.

  1. On larger devices we hide the first thead tr th element with display: none

  2. The first and second td elements inside each tbody row need to be set as position: absolute to avoid duplicate content

    This slope graph concept is far from perfect for use in real-world situations. The fact that you need to manually render each point of data yourself makes this implementation quite annoying for more in-depth projects.

    But it was fun to mess around with and create, so who cares!
