pasted data into data.csv and code into index.html from Mike Bostock's Stacked Bar example chart at http://bl.ocks.org/mbostock/3886208
removed the '65 Years and Over' column from data.csv to test rendering the chart with a bin removed.
removed the '45 to 64 Years' column from data.csv as well.  Now the chart shows 5 bins, which is the number of media types we have in the Europeana data.
replaced the age bins by state data with the media types bins by language data from europeana in data.csv.  The age bins by state labels remain.
changed the column header 'Under 5 Years' to 'Image' in data.csv to test renaming labels.
replaced all other column headers with the remaining media types from the Europeana collection
replaced the column header 'State' with 'language' in data.csv.  The chart fails to render, as the d3js code specifically refers to this column header.
in index.html replaced all occurences of 'State' with 'language'.  The chart now renders, as the connection with data.csv through the 'language' column header has been restored.
added 20 pixels to the width of the chart so that the y-axis label 'Population' is no longer occluded by the left-most bar
changed the text attribute of the y-axis label svg element to 'items indexed by Europeana' from 'Population'
changed the colors of the bins on the chart by commenting out two of the original seven colors #7b6888 and #6b486b specified in the range attribute of the d3 ordinal color scale
