Blockchain Legislation Friendliness (Passed only)
This choropleth map of the United States visualizes blockchain legislation friendliness across 14 states, with color intensity representing a legislative score. Using D3 v4’s geoAlbersUsa projection and geoPath generator, the visualization renders state boundaries as SVG paths. The color scale maps values from deep green (high friendliness, e.g., Hawaii at 6) to pale yellow (low friendliness, e.g., Wyoming at 0.5) and white for negative values (e.g., Alabama at -4). A gradient legend with an axis on the right provides the value-to-color mapping, with the underlying data loaded from a CSV file and merged with US state GeoJSON. The chart highlights only states with passed blockchain legislation, leaving others blank, while the legend uses a linear color ramp to indicate relative friendliness levels.# Blockchain Legislation Friendliness (Passed only)
## Overview
This choropleth map visualizes the friendliness of blockchain legislation across US states, highlighting only those states with passed legislation. The visualization uses a diverging color scale to represent the relative friendliness scores, ranging from green (friendly) to yellow (unfriendly), with unmentioned states left white.
## Visualization Design
The map uses an Albers USA projection to create a proportional representation of the contiguous United States, Alaska, and Hawaii. Each state is colored based on a "friendliness" score derived from a linear color ramp:
- **High scores** (e.g., Hawaii at 6.0) render in dark green
- **Low scores** (e.g., Alabama at -4.0) render in light yellow-green
- States without data are left white
## Interactivity
The visualization includes a vertical color legend on the left side of the map. The legend displays a linear gradient from dark green (high friendliness) to light yellow-green (low friendliness), with an axis labeled using the actual data values. The state boundaries are rendered in gray with a white fill for states without data.
## Data & Design
The choropleth map visualizes blockchain legislation friendliness scores for US states, with darker green shades indicating friendlier legislation and lighter shades indicating less friendly legislation. Only states with data are colored, creating a clear visual separation between measured and unmeasured states.
This example uses d3.geoAlbersUsa() projection to render the map and d3.geoPath() to generate the SVG paths for each state. The color scale is a linear gradient from light yellow-green to dark green, mapping the range of legislation scores from -4 (least friendly) to 6 (most friendly).

<h2>Blockchain Legislation Friendliness (Passed only)</h2>
<p>A choropleth map of the United States showing the relative friendliness of blockchain legislation across states. The color scale ranges from light yellow (less friendly) to dark green (more friendly), with values based on a compiled dataset of legislative scores. States without data are left white, and a legend indicates the score range.</p>
