+# LargeVis
 This is the *official* implementation of the **LargeVis** model by the original authors, which is used to visualize large-scale and high-dimensional data [(Tang, Liu, Zhang and Mei)](https://arxiv.org/abs/1602.00370). It now supports visualizing both high-dimensional feature vectors and networks. The package also contains a very efficient algorithm for constructing K-nearest neighbor graph (K-NNG).
 
 Contact person: Jian Tang, tangjianpku@gmail.com. This work is done when the author is in Microsoft Research Asia.

-##Usage
+## Usage
 LargeVis is suitable for visualizing both high-dimensional feature vectors and networks. For high-dimensional feature vectors, the format of input file should be as follows: the first line specifies the number of feature vectors and the dimensionality (500 vectors with 10 dimensions in the following example), and each of the next 500 lines describes one feature vector with 10 float numbers.

 * `-perp`: The perplexity used for deciding edge weights in K-NNG. Default is 50.
