The main question one should be able to answer is: who are the major donors and to which countries do they donate the most and how much? And conversely, who are the major receivers and which countries do they receive from the most and how much? We only care about the top 10 recipients and the top 20 donors (over the whole time) for this question. For this question, I chose to experiment with matrix (1.1) and fixed-layout visualizations (1.2 and 1.3). We can divide our data into two categories, donors and recipients, so I felt these types of visualizations were particularly appropriate and effective. I tried creating a force-directed graph, but the end result was cluttered. Furthermore, the degree of each node is at most 2, so the nodes don't really create a structure, which is the primary focus of force-directed graphs. Therefore, I opted for fixed-layout visualizations. I think the Sankey diagram better delineates between donors and recipient since each group is on their respective side. However, the donors and recipients are not mutually exclusive groups; South Korea, Saudi Arabia, and Kuwait have both donated and received money. This detail can be easy to skip over in the matrix and Sankey visualizations, but the fixed-layout diagram makes this clearer. `46:Tb5e,{ const cellSize = 30; const tileWidth = donors.size * cellSize; const tileHeight = recipients.size * cellSize; const visWidth = tileWidth + heatMargin.left + heatMargin.right; const visHeight = tileHeight + heatMargin.top + heatMargin.bottom; const svg = d3 .create('svg') .attr('width', visWidth) .attr('height', visHeight); const g = svg .append("g") .attr("transform", `translate(${heatMargin.left}, ${heatMargin.top})`); const y = d3 .scaleBand() .domain(recipients) .range([0, tileHeight]) .paddingInner(0.1); const x = d3 .scaleBand() .domain(donors) .range([0, tileWidth]) .paddingInner(0.1); const xAxis = d3.axisTop(x).tickSize(0); const yAxis = d3.axisLeft(y).tickSize(0); axisText(g, { name: 'x', axis: xAxis }, heatMargin); axisText(g, { name: 'y', axis: yAxis }, heatMargin); const xPadding = x.step() * x.paddingInner(); const yPadding = y.step() * y.paddingInner(); background(g, x, y, tileWidth, tileHeight, visWidth, visHeight); g.append('g') .selectAll('rect') .data(data.links) .join('rect') .attr('x', d => x(d.source)) .attr('y', d => y(d.target)) .attr('width', x.bandwidth()) .attr('height', y.bandwidth()) .attr('fill', d => donationIntensity(d.value)) .on('mouseenter', mouseEnter) .on('mouseleave', mouseLeave); const tooltip = g.append('g').attr('visibility', 'hidden'); const tooltipHeight = 15; const tooltipRect = tooltip .append('rect') .attr('fill', darkgray) .attr('rx', 5) .attr('height', tooltipHeight); const tooltipText = tooltip .append('text') .attr('fill', 'white') .attr('font-family', 'sans-serif') .attr('font-size', 10) .attr('dy', 2) .attr('dx', 2) .attr('dominant-baseline', 'hanging'); function mouseEnter(event, d) { d3.select(this) .attr('stroke', darkgray) .attr('stroke-width', yPadding / 2); tooltipText.text( `${[d.source, d.target].join(" → ")}\n${formatValue(d.value)}` ); const labelWidth = tooltipText.node().getComputedTextLength(); tooltipRect.attr('width', labelWidth + 4); const xPos = x(d.source) + x.bandwidth(); const yPos = y(d.target) - tooltipHeight / 2; tooltip .attr('transform', `translate(${xPos},${yPos})`) .attr('visibility', 'visible'); } function mouseLeave(event, d) { d3.select(this).attr('stroke', 'none'); tooltip.attr('visibility', 'hidden'); } heatText(g, 'Donors', { location: 'x', margin: heatMargin, width: tileWidth, height: tileHeight }); heatText(g, 'Recipients', { location: 'y', margin: heatMargin, width: tileWidth, height: tileHeight }); heatText(g, visualization1Title, { location: 'title', margin: heatMargin, width: tileWidth, height: tileHeight }); return svg.node(); }47:T1028,{ const margin = { top: 40, right: 70, bottom: 10, left: 80 }; const visWidth = width; const visHeight = 650; const sankey = d3 .sankey() .nodeWidth(15) .nodePadding(10) .nodeSort(d3.descending) .linkSort(null) .extent([ [margin.left, margin.top], [visWidth - margin.right, visHeight - margin.bottom] ]); const { nodes, links } = sankey({ nodes: graph.nodes.map(d => ({ ...d })), links: graph.links .map(d => ({ ...d })) .sort((a, b) => d3.descending(a.value, b.value)) }); const svg = d3.create("svg").attr("viewBox", [0, 0, visWidth, visHeight]); svg .append("g") .selectAll("rect") .data(nodes) .join("rect") .attr("x", d => d.x0) .attr("y", d => d.y0) .attr("height", d => d.y1 - d.y0) .attr("width", d => d.x1 - d.x0) .attr('text-anchor', d => (d.x0 < visWidth / 2 ?

Focusing again on the top 10 recipients and top 20 donors how do the patterns of donations (who donates to whom and how much) change over time? Are there sudden changes? Are there countries that always donate to other countries? Are there major shifts (say a country used to donate to a specific set of countries and then it changes to other countries)? For this visualization, each data point has four dimensions: donor, recipient, year, and amount. 1.1 illustrates how a 2D visualization can encode three of those dimensions: donor, recipient, and amount. There are several methods to the additional dimension, such as through faceting and/or small multiples. However, we're visualizing 40+ years' worth of data, and given the size of the matrix for a single year, we'd end up creating a large visualization that we probably couldn't fit in a single screen. Instead of making it easier to compare between years, I think scrolling would make it more difficult. We could mitigate this by aggregating the data, which will decrease the number of graphs we'd have to show. However, I felt making the visualization interactive would be a better solution because we typically aggregate data in consistent blocks e.g. every 5 years, 10 years but history doesn't occur that conveniently. Certain events may result in a country receiving more aid for some duration of time when it typically doesn't receive that much aid, and that trend would be difficult to see if we aggregate the data. Since the question's focus is not on the actual magnitudes but patterns, I chose to scale the data locally. This makes it easier to see who donated or received the most within a year (our eyes are immediately drawn to the darker cells), and therefore makes it easier to compare between years. `4f:Td1e,{ const cellSize = 30;

What composition (distribution) of purposes do the donations between each pair of countries have? Are there countries that donate to a given country using multiple purposes? Or do countries always donate using one single purpose when donating to another country? The same as the previous question, we only care about the top 10 recipients and the top 20 donors here.\n\nFor visualization 2, I took a similar approach to visualization 1. We're essentially visualizing the same data, but with an added dimension: purposes. 2.1 is a matrix visualization just like 1.1, but color intensity is replaced by pie charts. 1.2 and 2.2 are also practically identical, except that the former uses color hue to encode the recipients, while the latter uses the channel to encode
