Charts?

There are two methods that I use that might suit your needs. Neither require add-ins or server components. Both do a good job.

1. Create bar charts using a solid gif and tables. If you are familiar with what <tr> and <td> and the like mean, then you can take your data, sort it, calculate how many data points per bar, calculate a bar length in pixels, and stretch a "flat color" gif to be that length for each bar. Horizontal bar charts are very easy and quick to make. You can get fancier too, like labeling the bars, putting the number of data points with each bar, make each clickable to see raw data, heighlight certain bars (just swop out the gif for one of a different color.

Want a vertical bar chart? It's a tad harder to do, but is doable if you have a good understanding of tables.

2. Another way I plot data is to CSS positioning. Once you understand about absolute and relative positions and what z-indexes mean, its a fairly simple matter to plot small dots (e.g., a 3x3 gif) wherever you want for each data point. I used the technique on the home page of www.mainecoastcondominiums.com to plot condo locations.
