P-Pdot Diagram
Period vs period derivative for pulsars and magnetars. Isolines show constant magnetic field strength (B) and characteristic age (τ). The death line marks the theoretical boundary below which radio emission ceases.

Galactic Heatmap
Top-down view of neutron star positions projected onto the Galactic plane (x/y). The Sun is located at x = -8.122 kpc. Concentration near the Sun reflects detection bias — closer objects are easier to observe. KDE mode uses Gaussian kernel density estimation with Silverman bandwidth — may take a few seconds for large datasets.
