However, with Starvation and Sickness/medicine bar comparisons, one notices North Africa (yellow) takes up proportionally more of the bar for the individual chart compared to the event chart. This suggests that events of Starvation and Sickness in North Africa account for larger groups of people than in the Horn of Africa or Sub-Saharan Africa, the other two regions that take up a predominant amount of space on the Starvation and Sickness bars. Looking at the numbers each chart summarizes at the end of its flow, there is a clear lead in both individual and event counts when looking at rates of drowning compared to any of the other top 5 causes of death. To best understand the impact the difference between looking at individual versus event rates of causes of death can have, let’s focus in on drowning. Impacting the most migrants, how can different perspectives on rates of drowning lead to different outcomes in migrant protections and policy? ` 2d:T27c6,async function drawChart() { // Data const dataset = await d3.json("https://raw.githubusercontent.com/mattlawhon/Data-viz/master/individual") // Accessors const sexAccessor = d => d.sex const sexes = ["male"] const sexIds = d3.range(sexes.length) const educationAccessor = d => d.education const educationNames = [ "Drowning", "Sickness_med", "Starvation", "Unknown", "Vehicle" ] const educationIds = d3.range(educationNames.length) const sesAccessor = d => d.ses const sesNames = ["Mediterranean", "Horn of Africa", "North Africa", "US-Mexico Border", "Sub-Saharan Africa"] const sesIds = d3.range(sesNames.length) // probabilities const stackedProbabilities = {} dataset.forEach(startingPoint => { const key = getStatusKey(startingPoint) let stackedProbability = 0 stackedProbabilities[key] = educationNames.map((education, i) => { stackedProbability += (startingPoint[education] / 100) if (i == educationNames.length - 1) { // account for rounding return 1 } else { return stackedProbability } }) }) // persons let currentPersonId = 0 function generatePerson(elapsed) { currentPersonId++ const sex = getRandomValue(sexIds) const ses = getRandomValue(sesIds) const statusKey = getStatusKey({ sex: sexes[sex], ses: sesNames[ses], }) const probabilities = stackedProbabilities[statusKey] const education = d3.bisect(probabilities, Math.random()) return { id: currentPersonId, sex, ses, education, startTime: elapsed + getRandomNumberInRange(-0.1, 0.1), yJitter: getRandomNumberInRange(-15, 15) } } // dimensions let dimensions = { width: d3.min([width, 1200]), height: 500, margin: { top: 10, right: 240, bottom: 10, left: 180, }, pathHeight: 65, endsBarsWidth: 25, endingBarPadding: 4, } dimensions.boundedWidth = dimensions.width - dimensions.margin.left - dimensions.margin.right dimensions.boundedHeight = dimensions.height - dimensions.margin.top - dimensions.margin.bottom // canvas const wrapper = d3.select("#wrapper") .append("svg") .attr("width", dimensions.width) .attr("height", dimensions.height) const bounds = wrapper.append("g") .style("transform", `translate(${dimensions.margin.left}px, ${dimensions.margin.top}px)`) // scales const xScale = d3.scaleLinear() .domain([0, 1]) .range([0, dimensions.boundedWidth]) .clamp(true) const startYScale = d3.scaleLinear() .domain([sesIds.length, -1]) .range([0, dimensions.boundedHeight]) const endYScale = d3.scaleLinear() .domain([educationIds.length, -1]) .range([0, dimensions.boundedHeight]) const linkLineGenerator = d3.line() .x((d, i) => i * (dimensions.boundedWidth / 5)) .y((d, i) => i <= 2 ?
