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.

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

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.
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.
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.
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.
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.
