There will always be a user missing some marker in arbitrary number of built-in markers. Much better is to provide an interface for custom markers.\r\n\r\nHowever, one huge benefit of built-in markers is that it's size and colors can be data-driven. This is something not easily achievable by custom SVG markers currently, but could be solved by SVG parameters: http://www.w3.org/TR/SVGParamPrimer/\r\n\r\nWhat do you think?"},"comment":{"url":"https://api.github.com/repos/mapnik/mapnik/issues/comments/164558038","html_url":"https://github.com/mapnik/mapnik/issues/3062#issuecomment-164558038","issue_url":"https://api.github.com/repos/mapnik/mapnik/issues/3062","id":164558038,"user":{"login":"jchamberlain","id":3923548,"avatar_url":"https://avatars.githubusercontent.com/u/3923548?v=3","gravatar_id":"","url":"https://api.github.com/users/jchamberlain","html_url":"https://github.com/jchamberlain","followers_url":"https://api.github.com/users/jchamberlain/followers","following_url":"https://api.github.com/users/jchamberlain/following{/other_user}","gists_url":"https://api.github.com/users/jchamberlain/gists{/gist_id}","starred_url":"https://api.github.com/users/jchamberlain/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jchamberlain/subscriptions","organizations_url":"https://api.github.com/users/jchamberlain/orgs","repos_url":"https://api.github.com/users/jchamberlain/repos","events_url":"https://api.github.com/users/jchamberlain/events{/privacy}","received_events_url":"https://api.github.com/users/jchamberlain/received_events","type":"User","site_admin":false},"created_at":"2015-12-14T21:01:10Z","updated_at":"2015-12-14T21:01:10Z","body":"Until seeing this thread just now I believed changing colors etc of the SVG wasn't possible because of what the docs say. The MarkersSymbolizer [reference](https://github.com/mapnik/mapnik/wiki/MarkersSymbolizer) says of the fill attribute, \"This property is only used when the marker is NOT an SVG graphic.\" @talaj, maybe you can fix that when you look into this."}}
