Sporthorse Foal Registrations II

an iteration on Sporthorse Foal Registrations by phoebebright

an example of using d3 + crossfilter together to make an svg map with linked bar charts

these additions and modifications were made made along the way:

• format code so that it’s comfortable for me
• comment out the title on the page, and use the text for the title of the bl.ock
• set .style('white-space', 'nowrap') so that for Northern Ireland and 1999 the bar’s text fit’s within the bar’s height
• on mouseover of the county bar the cf crossfilter object is filtered for only that county. then, updateMap function is called, which re-renders the map with only the selected county shaded. on mouseout of the county bar, the cf object is unfiltered and the updatemMap function is called once again. Now all of the counties on the map have data-driven fill colors.
• hide the breed code text
• abstract out the map svg out of index.html and into a separate file, ireland.svg. this is more difficult that you might think. these links proved to be quite helpful:

a comment:

when you mouse over the bar for Northern Ireland, none of those counties are shaded, even though there appears to be data for those counties. this is something to investigate more. if you know why this is, tweet at me or comment on the github gist.
