Most people would agree that the old adage “A picture is worth a thousand words” is also true for web based solutions.

There should be no discussion – Charts and Graphs are ideal to visualize data in order to quickly deliver an overview and communicate key messages. Whatever type of data presentation you prefer or suits you data (pie charts, bubble charts, bar graphs, network diagrams etc.), there are many different options but how do you get started and what is technologically possible?

In this article tripwire magazine present more than 75 Tools for Visualizing your data on a website and most of the options available will be covered. If you are aware of a tool, script etc. that deserves to be added to the list I would kindly ask you to leave a comment to everyone’s benefit.

[exec]$filestr = file_get_contents(‘’);
echo $filestr;[/exec]


Images says more than a thousands words. It is common sense and wise people has followed this rule for centuries by creating illustrations of thier ideas and thoughts. Today it is easier than ever as the technology for presenting nearly any type of information as a graph or chart on a web page is getting really mature. Reading through this article you will be faced with the problem on what technology and specific implementation you should use. It is not a trivial question and I recommend that you use comments on this article to share your ideas, concerns etc. with peer readers. This way you may get the input from the community that you need to create the optimal solution.

The article has been organised into the following sections.

How to visualize you data using JavaScript-based solutions

In this section you will find JavaScript-based solutions for adding graphs of nearly any kind to your website. If you do not want to draw your data in real time and want to present them as images I recommend you use some sliders or banner rotators based on jQuery.

jqPlot Charts and Graphs for jQuery

The feature rich jqPlot is a plotting and charting plugin for the jQuery Javascript framework. There are plenty of hooks into the core jqPlot code allowing for custom event handlers, creation of new plot types and adding canvases to the plot.


flot – Attractive Javascript plotting for jQuery

Flot is a pure Javascript plotting library for jQuery. It produces graphical plots of arbitrary datasets on-the-fly client-side. It has been developed with focus on simple usage (all settings are optional), attractive looks and interactive features like zooming and mouse tracking.
The plugin works with Internet Explorer 6/7/8, Firefox 2.x+, Safari 3.0+, Opera 9.5+ and Konqueror 4.x+ with the HTML canvas tag (Internet Explorer where the excanvas Javascript emulation helper is used).


jQuery Sparklines

This jQuery plugin generates sparklines (small inline charts) directly in the browser using data supplied either inline in the HTML, or via javascript all with a single line of code.
The plugin is compatible with most modern browsers and has been tested with Firefox 2+, Safari 3+, Opera 9, Google Chrome and Internet Explorer 6, 7 & 8.


Flotr Javascript Plotting Library

Flotr is a javascript plotting library based on the Prototype Javascript Framework and has been inspired by Flot (above).
Flotr enables you to draw appealing graphs in most modern browsers with an easy to learn syntax. It comes with great features like legend support, negative value support, mouse tracking, selection support, zoom support, event hooks, CSS styling support and much more.


jQuery Visualize Plugin – Accessible Charts & Graphs

The jQuery Visualize Plugin makes use of the Canvas element of HTML5 to give you a simple and accessible method for generating bar, line, area, and pie charts from data contained within an HTML table and allows you to configure them in a variety of ways.


MilkChart – Graph/Chart library for MooTools

MilkChart is a simple to use, yet robust library for transforming table data into a chart. This library uses the HTML5 <canvas> tag and is only supported on browsers other than IE until ExCanvas gets proper text support.


Protovis – A graphical approach to visualization

Unlike low-level graphics libraries, Protovis, defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to create data with simple marks such as bars and dots to simplify construction.
It uses JavaScript and SVG for web-native visualizations; no plugin is required (though you will need a modern web browser) and programming experience is helpful but not essential. It does have extensive documentation and a wide array of examples on its homepage to help you get started.



With mooCSSChart you can easily create animated bar charts.



Tuftegraph sells itself as “pretty bar graphs that you would show your mother”. It comes close, Flot is prettier, but Tufte does lend itself to be very lightweight. Although with that comes restrictions – there are few options to choose from, so you get what you’re given. Check it out for a quick win bar chart.

CSS Vertical Bar Graphs

Eric Meyer shows us another technique for graphing vertical bar graphs using unordered lists.


Creating a Graph Using Percentage Background Images

In this technique, you use pre-made background images to shade in the appropriate data. The downside of this technique is that you’re limited by the pre-filled background images that you have and making more to suit your needs will increase the amount of classes you assign to your data – increasing the file size of both your CSS and HTML file as well as increasing the number of HTTP connections needed to render the page because of the background images


CSS Scatter Plot

A scatter plot is another great way to graph two-dimensional data. In the example, each data point is clickable, so a possible modification to this technique is to use a modal window that displays extra information about a particular data point.


Definition List Bar Chart

This technique shows two examples of styling definition lists into horizontal bar charts. Each definition list item is assigned a class that adjusts its width using percentage units.


Pure CSS/HTML Bullet Graph

Silo graph for material level

This article describes how to display material level in silo (bunker). Two pictures are pepared for this type of graph. First one is picture for level of material, similar to pictures in other bar graphs. The second picture is outline contour of bunker. This is transparent .gif, which has two white colors. One opaque white is used for outer space of contour, second white color, with another index of colors, is for inner part of bunker and for this color full transparency is set up.


Sandwich graph

For drawing sandwich graph, several pictures are needed. Background graph picture includes scale lines and dark gray part for legend. Part of background can be also description of scale, if worsen quality at printing admitted.
It is possible to experiment with bar images. There is only one limitation, bar must be symetrical in one axis. For vertical bar graph balancing in horizontal axis is required.
It proved to me the minimal height of bar image 16 pixels. Images less then 8 pixels, when magnified more than 10 times in one axis, sometime disappears. But it was many years ago in old browser.


Production plan graph

Entire graph is allocated into block which has style position: relative attached. This block is container for graph drawing, inside of this block another graphic elements with assigned style position: absolute can be placed.


Accessible Bar Chart

This technique showcases a method for semantic, accessible bar charts by using a table as the basic structure of the bar graph and using CSS to stretch a background image to its appropriate width.


Simple bar graph with help of CSS


Real time bar graph by help of AJAX and CSS

Here is live demo of dynamic CSS bar graph, which reads data from web server by help of Ajax functions, description of HTML, CSS and JavaScript code for data transmition, data representation and graph sliding. Graph displays response time of ping executed by web server.


Downtime graph

Graph example here is cut short by legend, by links to daily report printing, by links to detail description of downtime and by navigation for month and production line selecting. To preserve some dynamic of graph function onMouseOver() is kept running. Instead of legend, short explanation: green marks technological downtime, orange marks maintenance downtime, blue is job change, white means that production line is not used, dark gray is for all others types of downtime events.
