ead CSV -> parse to json
t csv = fs.readFileSync('./markers.csv').toString()
t markers = d3nMap.csvParse(csv)

ptional marker radius calculation
t radius = function (d) {
turn d.POP_2010 / 150000


ptional marker color fill 
t fill = function (d) {
nst colorScale = d3nMap.scaleThreshold()
.domain([1, 15, 20, 60])
.range(['rgb(255,245,240)', 'rgb(252,146,114)', 'rgb(203,24,29)', 'rgb(103,0,13)'])
turn colorScale(d.POP_2010 / 150000)


t map = d3nMap({ markers, radius, fill })
svgString() // returns <svg>
