This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population area ratio across 20 countries. Each circle’s position encodes GDP per capita on the x-axis and life expectancy on the y-axis, while its size reflects population density. The code uses d3.csv to load data, d3.scaleLinear for axes and bubble sizing, and d3.scaleOrdinal with schemeCategory10 for country colors. Interactive tooltips appear on mouseover, and a legend is built with SVG circles and text labels.

Activity-6_Question4

This bubble chart shows the correlation between GDP per capita, life expectancy, and population area ratio across 20 countries. Each circle’s position encodes GDP and life expectancy, while its size represents population density, with color distinguishing nations. A tooltip reveals exact values on hover. Built with D3 v7, it uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and SVG circles with mouse event handlers for interactivity. Data comes from `bubblechart.csv`, rendered with standard SVG elements and a categorical legend.

Activity6_Ques4

This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population area ratio across 20 countries. Each circle’s position encodes GDP per capita (x-axis) and life expectancy (y-axis), while its radius represents population density. The visualization uses D3 v7 with SVG rendering and interactive tooltips that display country-specific values on hover. A categorical color scale distinguishes countries, paired with a legend. The chart reads data from a CSV file and animates tooltip transitions, with circle opacity increasing on mouseover for enhanced readability.

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.

Question4

This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population area ratio across 20 countries, with each bubble’s size encoding population density and color identifying the country. The chart uses d3.csv() to load data from bubblechart.csv and renders circles via d3.scaleLinear for axes and bubble sizing, with a d3.scaleOrdinal and d3.schemeCategory10 for color mapping. Interactive tooltips are implemented with D3 event handlers (mouseover, mousemove, mouseleave) that display country details, while a static legend lists all countries beside color-coded dots.

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.

Question4_Bubble chart

This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population-area ratio for 20 countries. Each circle’s position maps GDP and life expectancy, while its radius encodes population density, with color distinguishing nations. Data is loaded via `d3.csv` from `bubblechart.csv`. The visualization uses `d3.scaleLinear` for axes and size, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and SVG circles with interactive tooltips on mouseover. A legend identifies each country.

Activity 8 - Q4.9

This bubble chart visualizes the correlation between life expectancy, population, and GDP per capita for a small set of countries. Each circle's x-axis position encodes life expectancy, its y-axis position encodes population, and its radius and color encode GDP per capita. The visualization uses D3.js (v7) with SVG rendering, and on hover, a tooltip displays the country name. The code applies `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with an `interpolateTurbo` color scale, and legends for GDP values and country colors. Data comes from the included `bubblechart.csv` file.

Activity6_Question4

This D3.js v7 bubble chart visualizes the relationship between GDP per capita, life expectancy, and population for countries in 2007, with bubbles positioned by GDP (on a log scale) and life expectancy, while bubble size encodes population. The chart uses `d3.scaleLog`, `d3.scaleSqrt`, and `d3.scaleOrdinal` to map data attributes, and renders in SVG with hover tooltips built via `d3.select` and the `.join` operator. Data is loaded from a CSV file containing country-level indicators, and the visualization includes legends for bubble size and continent color coding.
