<p><em>I am a huge sucker for simplistic and beautifully designed visual data on the web</em>. Most data tends to be graphed via line or bar systems - which is fine - but I think slope graphs are highly underrated. Let&#8217;s change that, shall we?</p>

<p>I&#8217;m basing this demo off the design patterns found in <a href="https://www.edwardtufte.com/tufte/books_vdqi">Edward Tufte&#8217;s visualization work</a>, specifically his slope graph designs:</p>

<p>For this concept we will actually be building this graph out of <code>tables</code> - crazy, right? The greatest benefit of rendering all the data inside of a <code>table</code> 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.</p>

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

<p>Now we need to design how our slope graph will look on larger screens &#47; desktops. For this instance, we will target these larger devices with a <code>min-width</code> media query of <code>800px</code>. The rest of the CSS might look a little confusing but I assure you it is quite simple.</p>

<p>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.</p>
