This bubble chart shows the correlation between birthrate, life expectancy, and GDP for 14 countries. The visualization uses animated SVG circles positioned by a linear scale for each axis, with bubble size and color encoding GDP via d3.scaleLinear and d3.scaleOrdinal with interpolateTurbo. A hover tooltip displays each country’s name using D3 event handlers, while a legend explains the GDP scale. The chart is implemented with d3.csv loading, axis generators, and data binding through `join`.

activity 6_question

This interactive bubble chart visualizes the correlation between birth rate, life expectancy, and GDP for fourteen countries. Each bubble's position encodes life expectancy (x-axis) and birth rate (y-axis), while its size reflects GDP and its color categorizes the country. Hovering over a bubble reveals its name. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color mapping, and `d3.cs` to load the `bubblechart.csv` data. A legend clarifies the GDP scale, and a tooltip appears on mouseover.

Fork of Assignment6_Question4.9

This bubble chart visualizes the relationship between GDP, life expectancy, and population for ten countries. Circles are positioned by GDP on the x-axis and life expectancy on the y-axis, with circle size representing population and color identifying each nation. The code uses D3 v6’s `scaleLinear`, `scaleSqrt`, and `d3.axisBottom`/`axisLeft` APIs, loading data from a local CSV. An SVG legend displays country-color mappings, with axis labels and a title clarifying the quantitative comparisons.

Fork of Bubble chart

This bubble chart visualizes the relationship between GDP, population, and life expectancy for 16 countries using a Cartesian coordinate system. Each circle's x-position corresponds to GDP, y-position to population, and radius to life expectancy, with color distinguishing countries. Built with D3 v7, the visualization uses `d3.scaleLinear()` for axes, `d3.scaleSqrt()` for bubble sizing, and `d3.scaleOrdinal()` for categorical coloring. Interactive hover effects enlarge bubbles and display country labels via `.on('mouseover')` handlers. Data loads from a local CSV file, rendered as SVG with animated transitions on user interaction.

Activity6_Task4_Qus4

This bubble chart visualizes the correlation between GDP per capita, population, and life expectancy across ten countries using D3 v7’s `d3.csv`, `d3.scaleLinear`, and `d3.scaleOrdinal` APIs. Bubbles are positioned by GDP (x-axis) and life expectancy (y-axis), with radius encoding population and color assigned per country. Animated SVG circles support interactive tooltips on mouseover and mouseleave events, revealing detailed numeric values for each nation. The visualization reads from the included `countries.csv` dataset and renders entirely in the browser via SVG.

Activity test

This bubble chart visualizes the correlation between average life expectancy, population, and GDP per capita for six countries using a CSV dataset. Each circle’s position maps to life expectancy and population on the x and y axes, while its radius encodes GDP per capita and its color distinguishes countries via a `d3.scaleOrdinal` with interpolated turbo colors. Interactive tooltips appear on hover using mouse events. A legend includes size reference circles and color swatches, all rendered with SVG in D3 v7.

Fork Question4-Bubble chart

This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population-area ratio for 20 countries. Each circle represents a country, with its x-axis position reflecting GDP per capita, y-axis position reflecting life expectancy, and bubble size proportional to population density. The chart uses D3.js v7 with the `scaleLinear` API for axis and bubble scaling, and the `scaleOrdinal` API for color assignment. Interactive tooltips display precise country data on hover, while an SVG-based legend identifies each nation’s color.

Activity6_Question 4

This D3.js bubble chart visualizes the correlation between GDP per capita, life expectancy, and population for 25 countries. The x-axis represents GDP in USD, the y-axis shows life expectancy in years, while bubble size encodes population in millions, and color distinguishes each country. The visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color assignment, and `d3.axisBottom` and `d3.axisLeft` for tick marks. Interactive tooltips appear on mouseover, displaying detailed country data, implemented with SVG `circle` elements and HTML div overlays. A legend with sample circles and labels explains the population scale.

4-Bubble_chart

This bubble chart visualizes the correlation between birthrate, life expectancy, and GDP across fourteen countries, using a D3.js SVG rendering with animated transitions. GDP scales bubble radius, while life expectancy and birthrate map to the x- and y-axes, with colors assigned via a turbo color scale. A tooltip displays each country’s name on hover, and a legend shows GDP values and country color keys. The chart uses D3’s CSV loader and linear scales, with data from the included CSV file.
