The Asian Art department even has 1800+ different time periods represented from various cultures and eras. Therefore, we wanted to create a donut chart that represented the most commonly represented periods of each department. However, for datasets with a huge number of time periods, many of the time periods would each only have under 50 art pieces, which is why we adapted our approach to only represent the top 15 most commonly represented periods of time for each department. In the visualization below, we display only five of the Met's departments because the other departments had a lack of period/time-related data, which forced us to use our "removeNulls" function to clean out the data. After doing so, we created a small-multiples chart of each of the departments where you can click on each donut chart for a more in-depth exploration of each department below. In the larger visualization, we have a tooltip explaining each of the section's period represented as well as the number of art pieces for each period represented. 31:T17d1,{ // the usual set up const {visWidth, visHeight, margin} = dimensions; const radius = 80 const svg = d3.create('svg') .attr('width', visWidth + margin.left + margin.right) .attr('height', visHeight + margin.top + margin.bottom) const g = svg.append('g') .attr('transform', `translate(${margin.left}, ${margin.top})`); g.append('text') .attr('x', visWidth - 100) .attr('y', visHeight - 100) .attr('font-family', 'sans-serif') .attr('text-anchor', 'middle') .attr('dominant-baseline', 'hanging') .text('CLEAR') .on('click', function (event, d) { onMouseExit(d) }) g.append('text') .attr('x', visWidth / 2) .attr('y', -margin.top + 5) .attr('font-family', 'sans-serif') .attr('text-anchor', 'middle') .attr('dominant-baseline', 'hanging') .text('Division of Each Met Art Department by Top 15 Most Represented Periods'); const cells = g.selectAll('g') .data(departmentArray) .join('g') .attr('transform', (d, i) => { const r = Math.floor(i / numberOfCols); const c = i % numberOfCols; // use the scales to get the x, y coordinates return `translate(${colScale(c)}, ${rowScale(r) + 10})`; }) cells.append('text') .join('text') .attr('font-size', 15) .attr('font-family', 'sans-serif') .attr("text-anchor", "middle") .attr("transform", `translate(${visWidth / 6 - 10}, ${visHeight/2 - 30})`) .text(d => d[0]) const pie3 = d3.pie().value(d => d.count) const arc = d3.arc() .innerRadius(40) .outerRadius(radius) .cornerRadius(4) const expanded = d3.create("svg") //.attr("opacity", 1) .style("background-color", "azure") .style("margin", "0 auto") .attr('width', visWidth + margin.left + margin.right) .attr('height', visHeight + margin.top + margin.bottom) .style("border-radius", "10px") const promptText = expanded.append('text') .join('text') .attr('font-size', 15) .attr('color', "black") .attr('font-family', 'sans-serif') .attr("text-anchor", "middle") .attr("transform", `translate (${(visWidth + margin.left + margin.right) / 2}, ${(visHeight + margin.left + margin.right) / 2})`) .text("Click on donut charts for an in-depth look at each department") const arcTool = d3.arc() .innerRadius(100) .outerRadius(radius*2.5) .cornerRadius(10) function update(data) { var donutHolder = expanded.selectAll('donut') .data(data) donutHolder.exit().remove(); donutHolder .enter() .append("path") .merge(donutHolder) .attr('d', arcTool) .attr("transform", `translate (${(visWidth + margin.left + margin.right) / 2}, ${(visHeight + margin.left + margin.right) / 2})`) .attr('fill', function(d) { //console.log(d) var periodsArray = d.data.periodsArray var colors = d3.quantize(t => d3.interpolateSpectral(t * 0.8 + 0.1), periodsArray.length); var colorScale = d3.scaleOrdinal().domain(periodsArray).range(d3.schemeSet3) // console.log(d) return colorScale(d.data.period)}) //.attr('fill', d => createColors(d.size)) // .attr("fill", d => color(N[d.data])) .attr("stroke", "grey") .style("stroke-width", "2px") .on("mouseover", function (event, d) { showToolTip(d.data.period, d.data.count, d) }) .on("mouseout", function () { tooltip3.style("opacity", 0) }) } const tooltip3 = d3.create("div") .attr("class", "tooltip3") .attr("id", "tooltip3") .html(`

With this, we launched a cursory investigation into what this looks like for each period. One of the problems that we encountered was the hundreds of mediums recorded for each period. For example, a period would have 3 mediums with greater than 200 pieces of art and then tens or hundreds more with < 50. To clean the data and prep for visualization, we decided to only show the top 5 mediums for each period and include an "Other" category to encompass all artwork. We also strategically chose periods that didn't include "Other" as the majority of pieces, so that data exploration would be more informative to users. An interesting feature is that the scrubber does a word search through all period keys and add the associated object to a combined array to representing all data for that period. This was done because of the many ways to represent a period present in the dataset. For example, there would be the period name, the period name and year, the period name and a range of years, an expanded version of the period name, etc. 34:T11c8,// Copyright 2021 Observable, Inc. // Released under the ISC license. // https://observablehq.com/@d3/donut-chart function DonutChartUnique(data, scrubPeriod, { name = ([x]) => x, // given d in data, returns the (ordinal) label value = ([, y]) => y, // given d in data, returns the (quantitative) value title, // given d in data, returns the title text width = 640, // outer width, in pixels height = 500, // outer height, in pixels innerRadius = Math.min(width, height) / 3, // inner radius of pie, in pixels (non-zero for donut) outerRadius = Math.min(width, height) / 2, // outer radius of pie, in pixels labelRadius = (innerRadius + outerRadius) / 2, // center radius of labels format = ",", // a format specifier for values (in the label) names, // array of names (the domain of the color scale) colors, // array of colors for names stroke = innerRadius > 0 ?

Therefore, we run "convertDepartment", which takes each of the second element objects from "departmentArray", and outputs it into an array of objects where each object again has the relevant period data, the count, as well as an array of the top 15 most represented periods. This is where we also cut off the top 15 and remove the rest of the periods. In addition, the reason why we stick the "periodsArray" data here, which is admittedly poor coding style, is because of the way that each of the donut arc data inputs are structured and the way that color works for the donut charts. In order for us to color the donut chart, we need to pre-emptively know what periods we're working with to create the domain for the color functions, but because each arc does not have access to the greater "pie" data, we need to stick the "periodsArray" in there in order for us to have access. 37:T41a,html` `38:T8c1,vis4 = { // give this svg an id so we can select it outside this cell const barChart = d3.select(html``); barChart.attr("width", svgWidth); barChart.attr("height", svgHeight); // add x-axis barChart.append("g") .attr('transform', `translate(${margin.left}, ${height4 + margin.top + spacing})`) .call(d3.axisBottom(xScale)) .selectAll("text") .attr("dx", "-.8em") .attr("dy", ".20em") .style("text-anchor", "end") .attr("transform", "rotate(-65)"); // add add y-axis barChart.append("g") .attr('transform', `translate(${margin.left}, ${margin.top + spacing})`) .call(d3.axisLeft(yScale)); // add chart title barChart.append("text") .attr("x", svgWidth / 2) .attr("y", 25) .attr("text-anchor", "middle") .text("Size of Each Department at the Met"); //add x-axis title barChart.append("text") .attr("x", margin.left + width4 / 2) .attr("y", svgHeight - 5) .attr("text-anchor", "middle") .attr("font-size", "14px") .text("Department"); // add y-axis title, remember that all transformations are around the (0, 0) origin barChart.append("text") .attr("x", -(margin.top + height4 / 2)) .attr("y", 15) .attr("transform", "rotate(-90") // rotate it by -90 degrees .attr("text-anchor", "middle") .attr("font-size", "14px") .text("Size of Department"); var tooltip = d3Tip() .attr('id', 'd3-tip') .html(function(event, d) { return d.size; }); const barGroup = barChart.append("g") // create a group to keep the bars .attr("class", "barGroup") .attr("transform", `translate(${margin.left}, ${margin.top})`); // shift all bars by the margin offset // Add rectangles here by binding the totalPopDataEntries array with rect elements barGroup.selectAll("rect") .data(departmentEntries) .join("rect") .attr("x", d => xScale(d.department)) .attr("y", d => yScale(d.size) + spacing) .attr("width", xScale.bandwidth()) .attr("height", d => height4 - yScale(d.size)) .attr("fill", d => colorScale(d.department)) .on('mouseover', tooltip.show) .on('mouseout', tooltip.hide) .call(tooltip); return barChart }39:[{"id":"5b7bb44872469fc6f9f4256d902fba909728666ad0d5263654ce95f4470ec90527fdc39a1d1b70490f457d65c31795d651a4afc0745f72351916e715fddc7352","href":"https://static.observableusercontent.com/files/5b7bb44872469fc6f9f4256d902fba909728666ad0d5263654ce95f4470ec90527fdc39a1d1b70490f457d65c31795d651a4afc0745f72351916e715fddc7352","name":"countries-110m.json","type":"application/json","lastModified":1679647890660.091,"size":107761}] 2d:{"id":"f83530dab084b024","slug":null,"title":"The Metropolitan Museum of Art's Collection","thumbnail":"eae13731285ff67caf5e11b47022cc2e3ed8fa27fdce480d7d80ec33c68da19c","access_level":"public","create_time":"$D2023-03-24T04:41:23.914Z","update_time":"$D2023-03-25T04:41:33.566Z","view_time":null,"first_public_time":"$D2023-03-24T04:41:23.914Z","fork":false,"stars":1,"starred":false,"owner":{"type":"team","id":"6b9013225a568399","login":"amberpat","name":"Amber Pat","avatar_url":"https://avatars-next.observableusercontent.com/dfe54cc52cdc5f7e5204083048e55f8c49188c24bd858dfcc660b5ba8f8ab8f3","tier":"starter_2024"},"version":523,"publish_version":null,"role":null,"authored":false,"authors":[{"type":"individual","id":"7fdbede0654713c6","login":"amberpat","name":"Amber Pat","avatar_url":"https://avatars-next.observableusercontent.com/dfe54cc52cdc5f7e5204083048e55f8c49188c24bd858dfcc660b5ba8f8ab8f3","tier":null}],"members":[{"type":"individual","id":"6ab815190d6714c2","login":"alee8599","name":"Alex Lee","avatar_url":"https://avatars-next.observableusercontent.com/a57cf8437e94e6cde2eeb24e0a5112989363f8edc6f0ad051f263f009f2c6087","tier":null,"role":"editor"},{"type":"individual","id":"7fdbede0654713c6","login":"amberpat","name":"Amber Pat","avatar_url":"https://avatars-next.observableusercontent.com/dfe54cc52cdc5f7e5204083048e55f8c49188c24bd858dfcc660b5ba8f8ab8f3","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":false,"trashed":false,"subscribed":null,"forks":1,"collection":null,"type":"notebook","body":{"title":"The Metropolitan Museum of Art's Collection","cells":[{"id":0,"value":"# The Metropolitan Museum of Art's Collection","pinned":false,"hidden":false,"mode":"md","author":"$undefined","summary":"$undefined"},{"id":7,"value":"md `#### Alex Lee and Amber Patrick`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined"},{"id":115,"value":"The Metropolitan Museum of Art is a longstanding fixture in New York City.

The problem, however, was 700+ uniquely named cultures that all had to be hand keyed to be associated with a modern country for mapping. To address this problem, we decided to trim the dataset such that only cultures with at least 10 pieces of art were included. After keying each culture to a modern country, we combined objects with the same country to get a dataset of all represented periods for a country and the total counts. With this, we extracted the period with the largest count as the most popular period and generated a total count across all periods as well.
