Dope Map problem legend

This example maps weekly influenza case counts across French regions for 2014, visualizing the data as a choropleth with a pink-to-red linear color scale. It builds the map with `d3.geoConicConformal` and renders region boundaries using `d3.geoPath`, while tooltips reveal region names on mouseover. The CSV data is joined to GeoJSON features by region name, and the map fills areas based on summed case values from December 2014.

Homework 3 - Bar & Grouped Charts with transition

This example demonstrates how bar charts can transition between a standard vertical presentation and a grouped, side-by-side layout. Using D3.js, the visualization animates the bars' positions and heights through a smooth transformation, highlighting changes in categorical data over time. The code leverages D3’s `transition.attrTween` and `d3.select` to interpolate between the two chart states. The underlying data is embedded directly in the HTML file, with the charts rendered as SVG elements using traditional D3 scales and axes.

A scatterplot displays the classic Iris flower dataset, plotting sepal width against petal width with points colored by species (red, lightgrey, lightblue). The visualization uses D3 v4 with SVG rendering, employing `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.symbol` for distinct marker shapes per species. A red line overlays the chart, computed via a custom linear regression function to show the overall trend across all measurements.
