Installing LLVM and Clang v3.2 on OS X

I'm assuming you need this version for Emscripten.

Don't worry, this script will not override your current installation of LLVM and Clang.

Be sure that you have:

Para la Argentina la proyección oficial es la Gauss-Kruger, y esta difiere bastante de la proyección Mercator que es normalmente utilizada en mapas digitales. Si queremos desplegar el territorio argentino de manera de lograr una representación armoniosa que conserve las formas y áreas, lo recomendable es usa Gauss-Kruger.

En D3.js no esta soportada esta proyeccion pero se puede optar por la proyección Mercator transversa d3.geo.transverseMercator() que es la base para la definición de la referencia cartográfica Gauss-Kruger. Esta proyección está definida dentro del plugin d3.geo.projection.js por lo que deberá ser cargado junto con d3.js.

Para poder calcular los parámetros necesarios para aplicar esta proyección es necesario calcular el centro geográfico de la Argentina continental, que está comprendida entre lo

Example illustrating zoom and pan with a "rolling" Mercator projection. Drag left-right to rotate projection cylinder, and up-down to translate, clamped by max absolute latitude. Ensures projection always fits properly in viewbox.

A quick overview of the node.js streams interface with basic examples.

This is based on @brycebaril's presentation, Node.js Streams2 Demystified

Overview

Streams are a first-class construct in Node.js for handling data.

Think of them as as lazy evaluation applied to data.

Zoomable/rotatable world globe that uses orthographic projection. Drag behavior is enhanced as described here: https://www.jasondavies.com/maps/rotate/

Performance is not good due to redrawing whole world upon zoom/drag.
