This bubble chart compares global cities by per-capita GDP, average temperature, and population, with bubble size encoding population and color encoding continent. It uses D3 v6 to render an SVG visualization, employing `d3.scaleLinear` for the x/y axes, `d3.scaleSqrt` for bubble radius, and `d3.scaleOrdinal` with a category color scheme. Data is loaded via `d3.csv` from a GitHub Gist, and the chart includes both color and size legends.

Activity6_Question4

This bubble chart shows the relationship between GDP and population for 20 global cities, with circle size encoding land area and color distinguishing cities. The visualization uses D3 v6 with SVG rendering, employing `d3.scaleLinear` for the x and y axes, `d3.scaleSqrt` for bubble radius, and `d3.scaleOrdinal` with `schemeCategory10` for color assignment. Interactive hover tooltips display city-specific population and GDP values, while axis labels identify the quantitative variables from the expanded_city_bubble_chart_dataset.csv file.

activity6_q9

A bubble chart maps population on the x-axis, area on the y-axis, and GDP to bubble size and color for 25 US cities. Each city’s bubble uses a distinct color from the `d3.interpolateTurbo` scale and is positioned using `d3.scaleLinear`. Hovering reveals a tooltip with city name and GDP. A legend displays GDP values, with circle sizes corresponding to the `z` scale. Data comes from `bubblechart.csv`.

Activity_6_Q4

This bubble chart visualizes the relationship between GDP, population, and economic growth for ten global cities. Each circle's x-position maps to GDP, y-position to population, and radius to growth rate, with individual city colors shown in a legend. The visualization uses D3 v7's `csv`, `scaleLinear`, and `scaleSqrt` functions to load the CSV data and map values. It renders to SVG with axis labels and tooltips, positioning the legend at the chart's right edge.

A6_Q4

This bubble chart displays city population and GDP on the y- and x-axes, with circle size and color encoding happiness scores. The visualization uses d3.csv to load a local CSV file and d3.scaleLinear, d3.scaleSqrt, and d3.axisBottom/Left to create scales and axes. SVG circles are rendered with fill colors ranging from lightgreen to darkgreen based on happiness, while city names appear as text labels near each bubble.

Activity6_Task4

A bubble chart visualizes 25 U.S. cities by plotting their population on the x-axis and area in square kilometers on the y-axis, with bubble size encoding GDP and color distinguishing each city. Hovering shows a tooltip with city details. Built with D3 v7, it uses `d3.scaleLinear` for axes and size, `d3.scaleOrdinal` with `d3.interpolateTurbo` for colors, and SVG circles with mouse event handlers. Data comes from `citydata.csv`, rendered as an animated SVG with a legend.

Activity 6 Task 4

This bubble chart visualizes the relationship between city population, GDP, and land area. Each circle’s position is mapped to GDP on the x-axis and population on the y-axis, while its radius encodes area via `d3.scaleSqrt`. Tooltips, styled through CSS with a lightsteelblue background, appear on mouseover using `d3.select` and `transition` to display city-specific data. The chart is rendered in SVG with axes generated by `d3.axisBottom` and `d3.axisLeft`, and colors are assigned using `d3.scaleOrdinal` with `d3.schemeCategory10`. The data is loaded from a CSV file using `d3.csv`.

activity6_question9

A bubble chart compares the population and GDP of 25 major U.S. cities, with bubble size representing city area and color intensity encoding GDP. The visualization uses D3.js v7 to load data from a CSV file and render SVG circles. Interactive tooltips appear on mouseover, showing each city's population and GDP. The chart includes labeled axes, a legend for area, and uses `d3.scaleLinear`, `d3.scaleSequential`, and `d3.interpolateBlues` for encoding.
