This stacked bar chart displays the proportional contribution of five energy sources—coal, gas, nuclear, hydro, and renewable—to electricity generation across six countries. Each bar segments by source share using percentages. The visualization uses D3 v7’s `d3.stack()` and `d3.scaleOrdinal` for coloring, with `d3.axisBottom` and `d3.axisLeft` for scales. Hovering over a segment reveals a tooltip showing the exact percentage via `d3.select` and `event.pageX`/`pageY` positioning, with data loaded from a local CSV.

Activity6_Question2

This stacked bar chart compares the proportional energy sources—coal, natural gas, nuclear, renewables, and other—across six countries using D3 v7’s `d3.stack`, `d3.scaleLinear`, and `d3.scaleBand`. Each bar segment is colored via a `d3.scaleOrdinal` color scale, and a hover tooltip reveals the exact percentage for each energy type. The SVG renders with custom axes and labels, reading the data from a CSV file that specifies each country’s energy mix as fractions.

Activity_6_Q3

This example visualizes the distribution of energy generation percentages across five energy sources (Coal, Solar, Wind, Nuclear, Hydro, and Natural Gas) using a stacked horizontal bar chart. It shows the proportional share of each source across five percentage categories, from below 10% to above 40%. The chart uses D3 v7’s `d3.stack()` and `d3.scaleBand()`, with SVG rendering and an ordinal color scale. Hovering over any bar segment highlights it and displays a tooltip with the exact percentage value, formatted via `d3.format()`. Data comes from a locally loaded CSV file.

Activity6_Task2

A grouped and stacked horizontal bar chart displays the percentage shares of renewable, fossil fuel, and nuclear electricity generation for ten countries. The visualization uses D3.js v7 with SVG rendering, loading data directly from a local CSV. It demonstrates `d3.stack()` for stacking the energy source series, `d3.scaleOrdinal()` for categorical colors, and `d3.axisBottom()` and `d3.axisLeft()` for axes. Interactive tooltips provide country-specific values when hovering over bars.

Activity 6_Question 2

This stacked horizontal bar chart displays the percentage distribution of energy generation across five sources, broken into five percentage ranges. The visualization uses d3.stack() to aggregate categories and d3.scaleBand() for the y-axis positioning, with d3.scaleOrdinal() assigning colors to each energy source. Interactive tooltips triggered by mouse events display precise percentage values for each segment. The chart includes axis labels, a title, and a legend, rendered as SVG elements with data loaded from a CSV file.

Activity-6-Q3

A stacked horizontal bar chart displays the percentage distribution of five energy sources—Coal, Solar, Wind, Nuclear, Hydro, and Natural Gas—across five categories from below 10% to above 40%. The chart uses d3.stack, d3.scaleOrdinal, d3.scaleBand, and d3.scaleLinear to render SVG rectangles, with tooltips on mouseover showing exact percentages via d3.format. A legend identifies each color-coded energy source. Data comes from the embedded energy_data.csv file.

Activity 6_Task 2

This stacked horizontal bar chart shows the percentage breakdown of energy sources—fossil fuels, nuclear, hydroelectric, solar, wind, and other renewables—for eight countries, with each bar segment colored by source and an interactive tooltip revealing exact values. The visualization uses D3 v7's `d3.stack()` to compute layered series, `d3.scaleBand()` and `d3.scaleLinear()` for axes, and `d3.scaleOrdinal()` for color mapping. Data is loaded from `data.csv` and rendered as SVG rectangles, with a custom mouseover tooltip built via D3 selections and a legend generated dynamically from the column headers.

Question 2

This stacked bar chart visualizes energy consumption by source across five countries (USA, China, India, Germany, Brazil) for 2023. The chart uses D3 v7 with `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, rendering stacked segments via `d3.stack().keys()` to represent Coal, Oil, Natural Gas, Renewable, and Nuclear proportions. Data loads from `energy_data.csv` using `d3.csv()`. A legend, generated with SVG groups, identifies each energy source, while custom colors are assigned through `d3.scaleOrdinal`.

4th visualisation

This visualization shows the composition of electricity generation by country, using stacked bar charts to break down each country’s total energy mix into six sources: coal, biofuel, hydro, nuclear, solar, and wind. The chart uses d3.csv to load data from a GitHub-hosted dataset, then applies d3.stack, d3.scaleBand, and d3.scaleLinear to compute and position the stacked segments. Color-coded bars via d3.scaleOrdinal distinguish the energy types, while interactive tooltips are provided through SVG title elements and axes are generated with d3.axisBottom.
