This bubble chart visualizes the relationship between healthcare spending (USD) and life expectancy across several countries from 1970 to 1974. Each bubble represents a country-year observation, with bubble size encoding the year and color distinguishing countries. Hovering over a bubble reveals a tooltip with exact values. The chart uses d3.v7's scaleLinear for axes and bubble sizing, scaleOrdinal for coloring, and SVG circles with transition-based tooltip interactions. Data is loaded from a local CSV file.

Activity6 Question4

This bubble chart displays the relationship between healthcare spending and life expectancy across several countries from 1970 to 1974. Each bubble’s size and position reflect spending, while color distinguishes countries. The visualization uses D3 v7 to load CSV data, scale linear axes, and render SVG circles. Interactive tooltips appear on mouseover, showing country-specific values. A legend encodes spending levels and country colors, with all elements animated through D3’s data joins and transitions.

Activity6-Question4

This bubble chart visualizes life expectancy versus healthcare spending across several countries from 1970 to 1974, with each circle’s size and color encoding spending magnitude and country identity. The visualization uses d3.csv to load the dataset, d3.scaleLinear for axes and bubble sizing, and d3.scaleOrdinal with d3.interpolateTurbo for country colors. Hover interactions trigger custom tooltips showing country, spending, and life expectancy values. The chart is rendered as an SVG with a legend for spending amounts, using d3.axisBottom and d3.axisLeft for axes.

Activity6_Question4

This interactive bubble chart visualizes the relationship between healthcare spending (in USD) and life expectancy across several countries from 1970 to 1974. Each circle’s size encodes spending amount, while its color distinguishes the country, with tooltips revealing exact values on hover. Built with D3 v7, it uses `d3.csv` to load data, `scaleLinear` for axes and bubble sizing, `scaleOrdinal` for color mapping, and `d3.axisBottom`/`axisLeft` for axes. The chart includes a legend for bubble sizes and country categories, rendered as SVG with animated tooltip transitions.

Activity6_Q4

This interactive bubble chart visualizes the relationship between healthcare spending (in USD) and life expectancy across several countries from 1970 to 1974. The visualization uses D3 v7 to render SVG circles, with bubble size proportionally mapped to spending values and color assigned per country via an ordinal scale with an interpolated Turbo colormap. A custom tooltip displays precise data on hover. The chart includes axis labels, bubble size legends, and a country color legend. Data is loaded from a local CSV file and rendered with animation-ready SVG elements.

Activity6_Question4

This animated bubble chart compares life expectancy against healthcare spending across multiple countries from 1970 to 1974. Each circle represents a country-year observation, with bubble size scaled to spending and color uniquely identifying each country. Hovering reveals a tooltip with exact values. The visualization uses D3 v7 with SVG rendering, employing `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` for color assignment, and CSV data loaded via `d3.csv`. Interactive tooltips respond to mouse events for enhanced data exploration.

Activity6-Question2

This visualization shows health expenditure and life expectancy across multiple countries from 1970 to 2007, using a horizontal stacked bar chart where each bar represents a country and segments show annual spending contributions. The chart uses D3 v7’s `d3.stack()` to create the stacked layout and `d3.scaleBand()` for country positioning, with years mapped to colors via `d3.scaleOrdinal()`. Hovering over any segment triggers mouseover and mousemove events that display a tooltip with the exact spending value for that country-year combination. The data comes from a CSV file loaded using `d3.csv()`.

Activity6_Question4.9

This example displays a bubble chart comparing GDP and average life expectancy across ten countries, with bubble size scaled to population and colors mapped to country-specific values. Built with D3 v6 and rendered as SVG, it uses `d3.csv` to load the dataset, `scaleLinear` and `scaleSqrt` for positioning and radius, and `d3.axisBottom`/`axisLeft` for axes. A custom legend lists each country with its corresponding color swatch, and labels identify the axes and chart title.

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.
