    <p>I'm making a Google Maps application that should support a high degree of customization of the displayed data. I want to allow the user to (among other things) pick between a wide assortment of shapes and colors for those shapes. Currently I have created PNGs of these shapes, each with 8 different color variations.</p> <p>Not only is it a lot of work to add additional shapes, but the color setting is also severely limited. I would like to allow the user to tune a few settings and create a brand new icon with them. For this to be possible in pure JavaScript, the Google Maps markers must be able to display Canvas data, which according to a (relatively old) blog post I found, it doesn't.</p> <p>Another option I can think of would be creating SVG images, but how do I apply the SVG to a Google Maps marker if I only have the SVG data in a JavaScript string?</p> <p>Anyway, the summarize the question; <strong>How can I create custom graphics on the fly and use them for a Google Maps marker?</strong></p>

    2. COJust thinking out loud here. If you don't want to create PNG markers for every colour, you could display two on top of each other, with the top one having a varying opacity. So a red one with a 50% opacity on top of a white one will be pink, for example. That would give you a lot of colour choices for a small number of predefined images.

    3. COInteresting idea indeed. It would be a total pain to implement though, since it requires two Markers per Marker, and I already have a large application build around "one marker per data row". It would also be a big performance hit

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
