The common perception among web designers is that the data charts that they upload on the website have to be packed with information. That is only partially correct! Yes, it is true that your data charts mean nothing to the online user unless you have relevant and valuable data in them. What is truer is that unless you present your data charts in an appealing, attractive way, your online visitors will be quickly repelled at their sight! Internet users have little time to deliberate over figures, unless you can provide them with the data numerical in a visually attractive format.
To ensure that your website is offering data charts in a manner that users like to read them, begin by picking the right colors and design. The color palette of the charts has to be dictated by the information that you want to pack into them. If you are talking about serious figures like malnutrition data or lives lost in a natural calamity, you cannot pick bright, vigorous colors. Soft, soothing colors will be a better option in these cases. On the other hand, for purely commercial purposes and to grab the attention of the users, make use of bright, shiny shades in your data charts.
Words lend a touch of panache to data charts. Pick your words carefully and with a lot of insight. If the design fails to draw attention (it might be so because users have varied tastes in colors and designs), the words will do the trick. You have to think of appropriate, relevant words that put across the right message without seeming too clever. Try not to pick words that are for the learned elite. A far wiser idea would be to pick up words that appeal to the general users and can grab eyeballs. To make data more appealing to online users, you have to simply and decode information for the convenience of the users. Unless you can do that, users will bounce away from your data chart without actually registering anything in their mind.
The idea of data charts is to communicate the message that you want to put across. If the words and the design are able to do that, you job is done!
