How to Create a CSS Chart – Basic Routine

Whatever CSS graph you need to create, whether it is a web version or graphical version for your startup presentation, to achieve the best result, you need to follow these five steps.

  1. Gather your information.
  2. Determine the type of chart. Is it an organizational CSS graph that is ideal for infographics or a numerical one that is used in dashboards and admins?
  3. Determine whether it will be static or interactive.
  4. Determine whether it will be generated dynamically from the live data, or you are going to build it from static data.
  5. Create an actual CSS graph. Here you can go two ways. The first one implies the utilization of third-party solutions like online services and specific JavaScript libraries that offer pre-made templates. The second one suggests creating everything from scratch that is ideal for custom and brand-tailored solutions.

Best Practices to Make a Killing CSS Graph

To unleash the potential of free CSS charts, follow these best practices:

  • Correctly define the type of CSS graph that you need. For example, do not use circle graphs for showing patterns or changes over time. Instead, use a line graph with exact numerical values.
  • Be careful when you need to show similar data values. Not all CSS charts are capable of dealing with this gracefully. For instance, circle graphs fail to deliver the distinction.
  • Add no more than 6-8 variables to one chart, especially to pie charts since too many wedges may confuse viewers.
  • Simplify color differentiation. It is better to use tones of the same color for the same group or class of data. For diverse groups, you can use contrast colors since the brain is quick to notice it. The simple way out is to create a gradation from dark to light tones. If you need to set focuses or prioritize some points, you can always refer to color psychology and apply some tricks to direct the attention towards the important things.
  • Make a CSS chart accessible. Like any other element of the user interface, it should be available to all people.
  • Make the CSS graph responsive and mobile-friendly to let it accommodate all the popular devices and hold consistency no matter what.
  • Make it browser compatible. If you create it from scratch, make sure you use CSS features that are widely supported, and the free CSS chart is correctly rendered across all boards.
  • Make it lightweight. Do not overload your website with excessive plugins and libraries.
  • Make it quick. Performance is critical. Data should be loaded quickly. If you cannot afford a fast connection and speed, make sure you provide good response for that. For instance, you can use a loader to notify about the delay.
  • Make it interactive. Hotspots, tooltips, pop-ups, and other dynamic features like hover effects and mouse-triggered animations may transform data perception into an actual storytelling experience that makes exploration engaging and impression long-lasting.
  • Structure your datasets in a clear order. You can arrange data clockwise or decreasing order from left to right (in RTL countries from right to left correspondingly).
  • Label graph with a head title, legend, and short descriptive sentence to avoid confusion. However, do not clutter the design with too many labels. Stick to a clean and minimal layout and ditch all the excess details. The rule of thumb, if the information is obvious, it does not require a label.
  • Animate data. Start with baby steps. Add a hover effect to focus the user’s attention on selected data unobtrusively.
  • Stick to one font, though use various weights. The bold version is excellent for the title, headings, and subheadings, whereas the light version is ideal for the legend, data labels, and body content.
  • Experiment with size to make it easy to tell the trends or data points apart across all sizes.
  • Make the chart as simple as possible. If you cannot do it, then divide data into several groups and create a CSS chart for each one.
