A population bubble chart displays projected and current population data for countries, using circle size to encode the 2022 population and color to distinguish categories. The visualization includes a custom tooltip that reveals country names and population values on hover. It loads JSON data from a GitHub-hosted dataset via `d3.json`, and renders the chart using `d3.select`, `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleOrdinal` within an SVG canvas, with event listeners for mouse interactions.

AI-generated description

In the map

  • data from an USGS API
  • circle size related to magnitude value
  • interaction: click circle and direct to a url
  • added color to the circles, according to depth (shallow, intermediate, deep)
  • added brush

In the scatter plot

  • added tooltip

Interaction:

Use a brush tool on the map to select the earthquakes that you want to display on the scatter plot.

Question 4

This bubble chart displays the relationship between GDP per capita, life expectancy, and population for countries across continents, with each circle’s size encoding population and color distinguishing continents. Built with D3.js v4 and rendered as SVG, it includes an interactive tooltip that shows the country name on hover, while highlighting and dimming by continent using CSS class selectors. The chart loads CSV data from a GitHub repository, uses `d3.scaleSqrt` for bubble sizing, `d3.scaleOrdinal` with `d3.schemeSet1` for colors, and animates opacity transitions for hover effects.

This example demonstrates two linked population visualizations for countries: a bubble chart comparing population in 1980 versus 2022, and a grouped bar chart showing population changes across four census years. Using D3 v7, the visualization loads data from a CSV file and renders SVG elements with scales and axes. The bubble chart uses `d3.scaleSqrt` for bubble radius, while the grouped bar chart employs `d3.scaleBand` and `d3.scaleOrdinal` for categorical positioning and color encoding, with both charts sharing axis labels and tooltips.

act 6 q7

This interactive bubble chart visualizes global population data by country, with circles sized proportionally to population and colored by continent. Users can toggle between four grouping modes—combine all countries, group by continent, place circles at country center coordinates, or scale by population—and switch between solid colors and country flag patterns. Built with D3 v4, the visualization uses `d3.forceSimulation` with custom force configurations for each layout, while transitions animate the bubbles when switching groupings. Hovering reveals country names and population counts, and a color-coded continent legend slides into view when relevant.

Activity6_q4

A bubble chart visualizes fertility, life expectancy, and population size for countries, using circle position for the first two variables and radius for population. The chart includes a color-coded legend by country and interactive tooltips that display the country name on hover. Built with D3 v7, it loads CSV data, renders SVG circles, and uses D3 scales for axes, bubble size, and ordinal color mapping with the interpolateTurbo color scheme.

Population Bubble Chart

This example visualizes population data for five countries as a bubble chart, mapping birth rate to the x-axis, life expectancy to the y-axis, and population to the size of each circle. Drawn as SVG circles with country labels, the chart also includes axes. The code uses D3 v6 scales (`d3.scaleLinear`, `d3.scaleSqrt`, `d3.scaleOrdinal`) with `d3.schemeCategory10` for colors and `d3.axisBottom` and `d3.axisLeft` to render the axes.

Activity6_Q4

This bubble chart shows the correlation between country populations in 2000, 2010, and 2020, with the x-axis, y-axis, and bubble size each representing one of those years. The code uses d3.csv to load population data, d3.scaleLinear for axes and bubble sizing, and d3.scaleOrdinal with d3.interpolateTurbo for coloring by country. Animated hover interactions reveal tooltips showing the country name, while a legend explains the 2020 population scale.

Activity6_Task4(q)

This bubble chart displays the relationship between total population and urban population across 35 countries, with bubble size encoding each nation’s yearly urban population change percentage. The visualization uses a categorical color scheme from Tableau to distinguish countries, accompanied by interactive tooltips that reveal precise figures on hover. Built with D3.js v7, the chart employs SVG rendering with three distinct scales: linear scales for both axes, a square-root scale for bubble sizing, and a legend for color coding. Data is loaded from a CSV file containing population statistics for global countries.

Activity6_Task4

This interactive D3 bubble chart visualizes global population data from a `countries.csv` file, representing each country as a circle whose radius encodes population via a square-root scale. Users can switch between grouping modes—combining all countries, grouping by continent, anchoring at country centers, or sorting by population—and toggle between color-coded continents and country flag patterns. The visualization leverages `d3.forceSimulation` for physics-based layout, with dynamic translation of the continent legend and animated transitions between groupings, all rendered as SVG with event-driven mouseover tooltips displaying country names and formatted population values.
