3 | ## AnyChart Bonfire
4 | This sample is created to show you the power of [GraphicsJS Library](http://www.graphicsjs.org/) which is a free part of AnyChart JavaScript Charts Library and can be used to vizualize virtually anthing. In this case it is a bonfire. A few lines of code and, due to the flexibility of our framework, you see an animated flame on your page: it may seem like a joke, but this goes anywhere: you can use AnyChart to create infographics, customize the smallest parts of your charts or create your own chart types.

135 | the terms of any separate license agreement you may have executed

137 |
138 | 6. Trademarks. This License does not grant permission to use the trade

147 | implied, including, without limitation, any warranties or conditions
148 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

155 | unless required by applicable law (such as deliberate and grossly
156 | negligent acts) or agreed to in writing, shall any Contributor be
157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a
159 | result of this License or out of the use or inability to use the

162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.

166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.
