Wiki

Bugs

When I generate an XML sitemap of the Wiki, using '?action=sitemap', not a single one of the spidered links actually works. There's usually an extra /AlgovizWiki in the URL. (aj 1 july 2008)

When I open the page for an individual entry, the 'Edit this entry' link at the bottom does not work. This time there's an extra Viz in the URL. Example: WaterlooSorting. (aj 1 july 2008)

Graph Utility

Bugs

• X-value strings are cut off by the bottom of the graph if they are too long. Artificially cut them to a certain length so it does not look cluttered.

Suggestions

• Have the option to exclude certain column values, for example if you want to compare the number of University of Maryland visualizations to Virginia Tech visualizations.
• Have option to rotate graph 90 degrees, so long text x-values are easier to read.
• Be able to save and load graph settings.
• Replace blank xvalues (for fields with no values) with a 'blank' or 'unknown' label.
• Give a count of unique values for a given query--so if I do a visualization based on the "works" field, ideally I get a count of 2 ("yes" and "no") or possible 3 (adding "blank" to the previous list)

Completed

• Add a link to the raw csv file in case it's useful (like http://thedigitalchimp.com/algoviz/datasets/2007.03.21.07.16.20.csv)

• Have the option to export the graph x/y values to a spreadsheet-friendly format (.csv, etc.).
• For a histogram, have options to sort columns by x-value (alphabetical) or by y-value (number).
• Matt noted that the graph doesn't render when:
  1. "Download Latest Dataset" is selected.
  2. Follow the rest of the steps normally, and render a graph.
  3. Go back to step 2 and select new fields to display.
  4. Render graph again, and it will display a broken image.
• Remove 'id' field from selection list, it is meant only for the sqlite database.

• Discards the first row of data (maybe you fixed this already, but I haven't checked)

• Be able to make a histogram on one field while limiting to a single value on another field (e.g. if I want to see a histogram of institutions but only over the set of Sorting visualizations)
